SLOW QUERIES
The slow query log is enabled.
Current long_query_time = 1.000000 sec.
You have 3595 out of 8019587 that take longer than 1.000000 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/5.1/en/point-in-time-recovery.html

WORKER THREADS
Current thread_cache_size = 256
Current threads_cached = 152
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 = 7
Historic max_used_connections = 157
The number of used connections is 31% of the configured maximum.
Your max_connections variable seems to be fine.

INNODB STATUS
Current InnoDB index space = 8 M
Current InnoDB data space = 11 M
Current InnoDB buffer pool free = 0 %
Current innodb_buffer_pool_size = 8 M
Depending on how much space your innodb indexes take up it may be safe
to increase this value to up to 2 / 3 of total system memory

MEMORY USAGE
Max Memory Ever Allocated : 1.15 G
Configured Max Per-thread Buffers : 3.23 G
Configured Max Global Buffers : 138 M
Configured Max Memory Limit : 3.36 G
Physical Memory : 31.26 G
Max memory limit seem to be within acceptable norms

KEY BUFFER
Current MyISAM index space = 71 M
Current key_buffer_size = 64 M
Key cache miss rate is 1 : 28348
Key buffer free ratio = 49 %
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 = 64 M
Current query_cache_used = 30 M
Current query_cache_limit = 64 M
Current Query cache Memory fill ratio = 47.90 %
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 = 2 M
Current read_rnd_buffer_size = 256 K
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 4.00 M
You have had 230366 queries where a join could not use an index properly
You have had 3 joins without keys that check for key usage after each row
join_buffer_size >= 4 M
This is not advised
You should enable "log-queries-not-using-indexes"
Then look for non indexed joins in the slow query log.

OPEN FILES LIMIT
Current open_files_limit = 30000 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_open_cache = 10000 tables
Current table_definition_cache = 10000 tables
You have a total of 1226 tables
You have 2564 open tables.
The table_cache value seems to be fine

TEMP TABLES
Current max_heap_table_size = 256 M
Current tmp_table_size = 256 M
Of 1170892 temp tables, 39% 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 = 128 K
Current table scan ratio = 66 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 85
You may benefit from selective use of InnoDB.
If you have a high concurrency of inserts on Dynamic row-length tables
consider setting 'concurrent_insert=2'.
