SLOW QUERIES
The slow query log is NOT enabled.
Your long_query_time may be too high, I typically set this under 5 sec.
MAX CONNECTIONS
Current max_connections = 800
Current threads_connected = 1
Historic max_used_connections = 17
The number of used connections is 2% of the configured maximum.
You are using less than 10% of your configured max_connections.
Lowering max_connections could help to avoid an over-allocation of memory
See “MEMORY USAGE” section to make sure you are not over-allocating
QUERY CACHE
Query cache is enabled
Current query_cache_size = 32 M
Current query_cache_used = 16 M
Current query_cach_limit = 4 M
Current Query cache fill ratio = 52.92 %
MySQL won’t cache query results that are larger than query_cache_limit in size
JOINS
Current join_buffer_size = 132.00 K
You have had 172 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.
TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 32 M
Of 94860 temp tables, 63% 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 LOCKING
Current Lock Wait ratio = 1 : 495
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′
