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

MySQL Version 5.0.67-community-log i686

Uptime = 2 days 10 hrs 22 min 14 sec
Avg. qps = 6
Total Questions = 1366252
Threads Connected = 1

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

runtime variables effects performance visit:

SLOW QUERIES
The slow query log is enabled.
Current long_query_time = 1 sec.
You have 84067 out of 1366291 that take longer than 1 sec. to complete
Your long_query_time seems to be fine

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 = 128
Current threads_cached = 31
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 50
Current threads_connected = 1
Historic max_used_connections = 32
The number of used connections is 64% of the configured maximum.
Your max_connections variable seems to be fine.

MEMORY USAGE
Max Memory Ever Allocated : 540 M
Configured Max Per-thread Buffers : 756 M
Configured Max Global Buffers : 57 M
Configured Max Memory Limit : 813 M
Physical Memory : 512 M

Max memory limit exceeds 90% of physical memory

KEY BUFFER
Current MyISAM index space = 38 M
Current key_buffer_size = 32 M
Key cache miss rate is 1 : 9550
Key buffer free ratio = 65 %
Your key_buffer_size seems to be fine

QUERY CACHE
Query cache is enabled
Current query_cache_size = 15 M
Current query_cache_used = 5 M
Current query_cache_limit = 4 M
Current Query cache Memory fill ratio = 34.79 %
Current query_cache_min_res_unit = 4 K
MySQL won't cache query results that are larger than query_cache_limit in size

SORT OPERATIONS
Current sort_buffer_size = 4 M
Current read_rnd_buffer_size = 4 M
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 3.00 M
You have had 7 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 = 4060 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 = 2000 tables
You have a total of 182 tables
You have 319 open tables.
The table_cache value seems to be fine

TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 32 M
Of 33885 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
Current read_buffer_size = 4 M
Current table scan ratio = 291 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 310
You may benefit from selective use of InnoDB.
