Uptime = days hrs min sec
Avg. qps = 5
Total Questions = 1707329
Threads Connected = 1

Server has been running for over 48hrs.
It should be safe to follow these recommendations

To find out more information on how each of these
runtime variables effects performance visit:
http://dev.mysql.com/doc/refman/4.1/en/server-system-variables.html
Visit http://www.mysql.com/products/enterprise/advisors.html
for info about MySQL's Enterprise Monitoring and Advisory Service

SLOW QUERIES
The slow query log is NOT enabled.
Current long_query_time = 10 sec.
You have 99 out of 1707343 that take longer than 10 sec. to complete
Your long_query_time may be too high, I typically set this under 5 sec.

BINARY UPDATE LOG
The binary update log is NOT enabled.
You will not be able to do point in time recovery
See http://dev.mysql.com/doc/refman/4.1/en/point-in-time-recovery.html

WORKER THREADS
Current thread_cache_size = 128
Current threads_cached = 85
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 500
Current threads_connected = 1
Historic max_used_connections = 86
The number of used connections is 17% of the configured maximum.
Your max_connections variable seems to be fine.

Key buffer fill ratio = %
./tuning-primer.sh: line 684: [: -ge: unary operator expected
./tuning-primer.sh: line 688: [: -le: unary operator expected
Your key_buffer_size seems to be fine

QUERY CACHE
./tuning-primer.sh: line 719: bc: command not found

Query cache is enabled
./tuning-primer.sh: line 331: bc: command not found

./tuning-primer.sh: line 742: [: -le: unary operator expected
./tuning-primer.sh: line 746: [: -ge: unary operator expected
MySQL won't cache query results that are larger than query_cache_limit in size

SORT OPERATIONS
./tuning-primer.sh: line 331: bc: command not found
Current sort_buffer_size = M
./tuning-primer.sh: line 331: bc: command not found
Current read_rnd_buffer_size = K
Sort buffer seems to be fine

JOINS
./tuning-primer.sh: line 331: bc: command not found
Current join_buffer_size = M
You have had 31 queries where a join could not use an index properly
You should enable "log-queries-not-using-indexes"
Then look for non indexed joins in the slow query log.
If you are unable to optimize your queries you may want to increase your
join_buffer_size to accommodate larger joins in one pass.

Note! This script will still suggest raising the join_buffer_size when
ANY joins not using indexes are found.

OPEN FILES LIMIT
Current open_files_limit = 2558 files
The open_files_limit should typically be set to at least 2x-3x
that of table_cache if you have heavy MyISAM usage.
Your open_files_limit value seems to be fine

TABLE CACHE
Current table_cache value = 1024 tables
You have a total of 1650 tables
You have 1022 open tables.
Current table_cache hit rate is 11%, while 99% of your table cache is in use
You should probably increase your table_cache

TEMP TABLES
./tuning-primer.sh: line 331: bc: command not found
Current max_heap_table_size = M
./tuning-primer.sh: line 331: bc: command not found
Current tmp_table_size = M
Of 91866 temp tables, 0% were created on disk
Effective in-memory tmp_table_size is limited to max_heap_table_size.
Created disk tmp tables ratio seems fine

TABLE SCANS
./tuning-primer.sh: line 331: bc: command not found
Current read_buffer_size = M
Current table scan ratio = 2109 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 979
You may benefit from selective use of InnoDB.
If you have long running SELECT's against MyISAM tables and perform
frequent updates consider setting 'low_priority_updates=1'

Böyle bir çıktı aldım nasıl bir yol izlemem lazım yardımcı olursan sevinirim iyinet.

-- MYSQL PERFORMANCE TUNING PRIMER --
             - By: Matthew Montgomery -

MySQL Version 5.0.32-Debian_7etch5-log i486

Uptime = 2 days 5 hrs 35 min 41 sec
Avg. qps = 30
Total Questions = 5949923
Threads Connected = 2

Server has been running for over 48hrs.
It should be safe to follow these recommendations

To find out more information on how each of these
runtime variables effects performance visit:
http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html
Visit http://www.mysql.com/products/enterprise/advisors.html
for info about MySQL's Enterprise Monitoring and Advisory Service

SLOW QUERIES
Current long_query_time = 2 sec.
You have 40630 out of 5949948 that take longer than 2 sec. to complete
The slow query log is enabled.
Your long_query_time seems to be fine

WORKER THREADS
Current thread_cache_size = 384
Current threads_cached = 133
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 200
Current threads_connected = 3
Historic max_used_connections = 136
The number of used connections is 68% of the configured maximum.
Your max_connections variable seems to be fine.

MEMORY USAGE
Max Memory Ever Allocated : 1 G
Configured Max Per-thread Buffers : 1 G
Configured Max Global Buffers : 306 M
Configured Max Memory Limit : 2 G
Physical Memory : 1.97 G

Max memory limit exceeds 90% of physical memory

KEY BUFFER
Current MyISAM index space = 306 M
Current key_buffer_size = 256 M
Key cache miss rate is 1 : 4036
Key buffer fill ratio = 44.00 %
Your key_buffer_size seems to be too high.
Perhaps you can use these resources elsewhere

QUERY CACHE
Query cache is enabled
Current query_cache_size = 40 M
Current query_cache_used = 24 M
Current query_cache_limit = 4 M
Current Query cache Memory fill ratio = 60.97 %
Current query_cache_min_res_unit = 4 K
Query Cache is 21 % fragmented
Run "FLUSH QUERY CACHE" periodically to defragment the query cache memory
If you have many small queries lower 'query_cache_min_res_unit' to reduce fragmentation.
MySQL won't cache query results that are larger than query_cache_limit in size

SORT OPERATIONS
Current sort_buffer_size = 2 M
Current record/read_rnd_buffer_size = 3 M
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 2.00 M
You have had 28 queries where a join could not use an index properly
You should enable "log-queries-not-using-indexes"
Then look for non indexed joins in the slow query log.
If you are unable to optimize your queries you may want to increase your
join_buffer_size to accommodate larger joins in one pass.

Note! This script will still suggest raising the join_buffer_size when
ANY joins not using indexes are found.

OPEN FILES LIMIT
Current open_files_limit = 2258 files
The open_files_limit should typically be set to at least 2x-3x
that of table_cache if you have heavy MyISAM usage.
You currently have open more than 75% of your open_files_limit
You should set a higher value for open_files_limit in my.cnf

TABLE CACHE
Current table_cache value = 1024 tables
You have a total of 772 tables
You have 1024 open tables.
Current table_cache hit rate is 53%, while 100% of your table cache is in use
You should probably increase your table_cache

TEMP TABLES
Current max_heap_table_size = 64 M
Current tmp_table_size = 128 M
Of 91458 temp tables, 31% were created on disk
Effective in-memory tmp_table_size is limited to max_heap_table_size.
Perhaps you should increase your tmp_table_size and/or max_heap_table_size
to reduce the number of disk-based temporary tables
Note! BLOB and TEXT columns are not allow in memory tables.
If you are using these columns raising these values might not impact your
ratio of on disk temp tables.

TABLE SCANS
Current read_buffer_size = 1 M
Current table scan ratio = 389 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 15
You may benefit from selective use of InnoDB.
If you have long running SELECT's against MyISAM tables and perform
frequent updates consider setting 'low_priority_updates=1'
If you have a high concurrency of inserts on Dynamic row-length tables
consider setting 'concurrent_insert=2'.

Perhaps you can use these resources elsewhere

QUERY CACHE
Query cache is supported but not enabled
Perhaps you should set the query_cache_size

SORT OPERATIONS

Current read_rnd_buffer_size = 256 K
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 132.00 K
You have had 213 queries where a join could not use an index properly
You should enable "log-queries-not-using-indexes"
Then look for non indexed joins in the slow query log.
If you are unable to optimize your queries you may want to increase your
join_buffer_size to accommodate larger joins in one pass.

Note! This script will still suggest raising the join_buffer_size when
ANY joins not using indexes are found.

OPEN FILES LIMIT
Current open_files_limit = 1024 files
The open_files_limit should typically be set to at least 2x-3x

Your open_files_limit value seems to be fine

TABLE CACHE
Current table_cache value = 64 tables
You have a total of 471 tables
You have 64 open tables.
Current table_cache hit rate is 0%, while 100% of your table cache is in use
You should probably increase your table_cache

TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 32 M
Of 93291 temp tables, 87% were created on disk
Effective in-memory tmp_table_size is limited to max_heap_table_size.
Perhaps you should increase your tmp_table_size and/or max_heap_table_size
to reduce the number of disk-based temporary tables
Note! BLOB and TEXT columns are not allow in memory tables.
If you are using these columns raising these values might not impact your
ratio of on disk temp tables.

TABLE SCANS
Current read_buffer_size = 128 K
Current table scan ratio = 200 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 1350
You may benefit from selective use of InnoDB.
If you have long running SELECT's against MyISAM tables and perform
frequent updates consider setting 'low_priority_updates=1'
If you have a high concurrency of inserts on Dynamic row-length tables
consider setting 'concurrent_insert=2'.

Merhaba,

tuning-primer kurulumunu az evvel yaptım. Sanırım çıktıları ancak bir kaç gün sonra vermem faydalı olacak.

Serverde vBulletin+vBSEO kurulu. Bu hafta xCache kurulumuda yapıldı. Server bilgilerim aşağıda yer almakta.

Sitenin günlük tekili 50K ve 15 dakika cookie timeout online: 1250

tuning-primer kurmadan evvel my.cnf içeriği aşağıdaki gibiydi.

Fakat bir çok ayarda burada gördüğüm örneklere göre ve büyük vir vB foruma göre arada uçurumlar vardı, şu şekilde kafama göre değişiklikler yaptım ama mutlaka fazla ya da eksik satırlar ve rakamlar olduğunu düşünüyorum. Sayın iyinet admini ve diğer arkadaşların fikir ve önerilerini beklemekteyim.

Physical Memory : 7.79 G



Max memory limit exceeds 90% of physical memory 



KEY BUFFER

Current MyISAM index space = 967 M

Current key_buffer_size = 384 M

Key cache miss rate is 1 : 17679

Key buffer fill ratio = 99.00 %

You could increase key_buffer_size

It is safe to raise this up to 1/4 of total system memory;

assuming this is a dedicated database server.



QUERY CACHE

Query cache is enabled

Current query_cache_size = 256 M

Current query_cache_used = 97 M

Current query_cache_limit = 8 M

Current Query cache Memory fill ratio = 38.15 %

Current query_cache_min_res_unit = 4 K

Query Cache is 27 % fragmented

Run "FLUSH QUERY CACHE" periodically to defragment the query cache memory

If you have many small queries lower 'query_cache_min_res_unit' to reduce fragme                                                                             ntation.

MySQL won't cache query results that are larger than query_cache_limit in size



SORT OPERATIONS

Current sort_buffer_size = 8 M

Current read_rnd_buffer_size = 768 K

Sort buffer seems to be fine



JOINS

Current join_buffer_size = 2.00 M

You have had 18543 queries where a join could not use an index properly

You should enable "log-queries-not-using-indexes"

Then look for non indexed joins in the slow query log.

If you are unable to optimize your queries you may want to increase your

join_buffer_size to accommodate larger joins in one pass.



Note! This script will still suggest raising the join_buffer_size when

ANY joins not using indexes are found.



OPEN FILES LIMIT

Current open_files_limit = 17260 files

The open_files_limit should typically be set to at least 2x-3x

that of table_cache if you have heavy MyISAM usage.

Your open_files_limit value seems to be fine



TABLE CACHE

Current table_cache value = 8000 tables

You have a total of 462 tables

You have 1011 open tables.

The table_cache value seems to be fine



TEMP TABLES

Current max_heap_table_size = 64 M

Current tmp_table_size = 64 M

Of 287383 temp tables, 41% were created on disk

Perhaps you should increase your tmp_table_size and/or max_heap_table_size

to reduce the number of disk-based temporary tables

Note! BLOB and TEXT columns are not allow in memory tables.

If you are using these columns raising these values might not impact your

ratio of on disk temp tables.



TABLE SCANS

Current read_buffer_size = 2 M

Current table scan ratio = 40288 : 1

You have a high ratio of sequential access requests to SELECTs

You may benefit from raising read_buffer_size and/or improving your use of index                                                                             es.

You have 34323 out of 12044659 that take longer than 10 sec. to complete
Your long_query_time may be too high, I typically set this under 5 sec.

BINARY UPDATE LOG
The binary update log is NOT enabled.
You will not be able to do point in time recovery
See http://dev.mysql.com/doc/refman/5.0/en/point-in-time-recovery.html

WORKER THREADS
Current thread_cache_size = 0
Current threads_cached = 0
Current threads_per_sec = 8
Historic threads_per_sec = 1
Threads created per/sec are overrunning threads cached
You should raise thread_cache_size

MAX CONNECTIONS
Current max_connections = 100
Current threads_connected = 8
Historic max_used_connections = 70
The number of used connections is 70% of the configured maximum.
Your max_connections variable seems to be fine.

Max memory limit seem to be within acceptable norms

KEY BUFFER
./tuning-primer.sh: line 668: bc: command not found
./tuning-primer.sh: line 669: bc: command not found
./tuning-primer.sh: line 350: bc: command not found
Current MyISAM index space =  M
./tuning-primer.sh: line 350: bc: command not found
Current key_buffer_size =  M
Key cache miss rate is 1 : 31639
Key buffer free ratio =  %
./tuning-primer.sh: line 706: [: -le: unary operator expected
Your key_buffer_size seems to be too high.
Perhaps you can use these resources elsewhere

QUERY CACHE
Query cache is supported but not enabled
Perhaps you should set the query_cache_size

SORT OPERATIONS
./tuning-primer.sh: line 350: bc: command not found
Current sort_buffer_size =  M
./tuning-primer.sh: line 350: bc: command not found
Current read_rnd_buffer_size =  K
Sort buffer seems to be fine

JOINS
./tuning-primer.sh: line 350: bc: command not found
Current join_buffer_size =  K
You have had 0 queries where a join could not use an index properly
Your joins seem to be using indexes properly

OPEN FILES LIMIT
Current open_files_limit = 1024 files
The open_files_limit should typically be set to at least 2x-3x
that of table_cache if you have heavy MyISAM usage.
Your open_files_limit value seems to be fine

TABLE CACHE
Current table_cache value = 64 tables
You have a total of 138 tables
You have 64 open tables.
Current table_cache hit rate is 0%, while 100% of your table cache is in use
You should probably increase your table_cache

TEMP TABLES
./tuning-primer.sh: line 350: bc: command not found
Current max_heap_table_size =  M
./tuning-primer.sh: line 350: bc: command not found
Current tmp_table_size =  M
Of 2002022 temp tables, 48% were created on disk
Effective in-memory tmp_table_size is limited to max_heap_table_size.
Perhaps you should increase your tmp_table_size and/or max_heap_table_size
to reduce the number of disk-based temporary tables
Note! BLOB and TEXT columns are not allow in memory tables.
If you are using these columns raising these values might not impact your
ratio of on disk temp tables.

TABLE SCANS
./tuning-primer.sh: line 350: bc: command not found
Current read_buffer_size =  K
Current table scan ratio = 435 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 461
You may benefit from selective use of InnoDB.
If you have long running SELECT's against MyISAM tables and perform
frequent updates consider setting 'low_priority_updates=1'
If you have a high concurrency of inserts on Dynamic row-length tables
consider setting 'concurrent_insert=2'.
