-- MYSQL PERFORMANCE TUNING PRIMER --
- By: Matthew Montgomery -
MySQL Version 5.5.54-0+deb8u1 x86_64
Uptime = 0 days 0 hrs 15 min 33 sec
Avg. qps = 43
Total Questions = 40522
Threads Connected = 133
Warning: Server has not been running for at least 48hrs.
It may not be safe to use these recommendations
To find out more information on how each of these
runtime variables effects performance visit:
for info about MySQL's Enterprise Monitoring and Advisory Service
The slow query log is NOT enabled.
Current long_query_time = 50.000000 sec.
You have 75 out of 40632 that take longer than 50.000000 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
Current thread_cache_size = 80
Current threads_cached = 24
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine
Current max_connections = 400
Current threads_connected = 133
Historic max_used_connections = 160
The number of used connections is 40% of the configured maximum.
Your max_connections variable seems to be fine.
Current InnoDB index space = 5 M
Current InnoDB data space = 141 M
Current InnoDB buffer pool free = 79 %
Current innodb_buffer_pool_size = 128 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
Max Memory Ever Allocated : 9.83 G
Configured Max Per-thread Buffers : 23.58 G
Configured Max Global Buffers : 416 M
Configured Max Memory Limit : 23.99 G
Physical Memory : 15.40 G
Max memory limit exceeds 90% of physical memory
Current MyISAM index space = 16 M
Current key_buffer_size = 256 M
Key cache miss rate is 1 : 281
Key buffer free ratio = 81 %
Your key_buffer_size seems to be fine
Query cache is enabled
Current query_cache_size = 16 M
Current query_cache_used = 12 M
Current query_cache_limit = 1 M
Current Query cache Memory fill ratio = 77.56 %
Current query_cache_min_res_unit = 4 K
MySQL won't cache query results that are larger than query_cache_limit in size
Current sort_buffer_size = 10 M
Current read_rnd_buffer_size = 40 M
Sort buffer seems to be fine
Current join_buffer_size = 132.00 K
You have had 520 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 = 2000 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
Current table_open_cache = 256 tables
Current table_definition_cache = 400 tables
You have a total of 583 tables
You have 351 open tables.
Current table_cache hit rate is 6%
, while 137% of your table cache is in use
You should probably increase your table_cache
You should probably increase your table_definition_cache value.
Current max_heap_table_size = 16 M
Current tmp_table_size = 16 M
Of 1700 temp tables, 5% were created on disk
Created disk tmp tables ratio seems fine
Current read_buffer_size = 10 M
Current table scan ratio = 3291909 : 1
read_buffer_size is over 8 MB there is probably no need for such a large read_buffer
Current Lock Wait ratio = 0 : 41480
Your table locking seems to be fine
