-- MYSQL PERFORMANCE TUNING PRIMER --
- By: Matthew Montgomery -
MySQL Version 5.0.51a-community i686
Uptime = 0 days 10 hrs 29 min 57 sec
Avg. qps = 170
Total Questions = 6444095
Threads Connected = 3
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:
MySQL :: MySQL 5.0 Reference Manual :: 5.1.3 System Variables
Visit MySQL :: MySQL Enterprise Advisors
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 122 out of 6444116 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 MySQL :: MySQL 5.0 Reference Manual :: 6.3 Point-in-Time Recovery
WORKER THREADS
Current thread_cache_size = 0
Current threads_cached = 0
Current threads_per_sec = 2
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 = 2
Historic max_used_connections = 21
The number of used connections is 21% of the configured maximum.
Your max_connections variable seems to be fine.
MEMORY USAGE
Max Memory Ever Allocated : 74 M
Configured Max Per-thread Buffers : 268 M
Configured Max Global Buffers : 17 M
Configured Max Memory Limit : 286 M
Physical Memory : 1010.31 M
Max memory limit seem to be within acceptable norms
KEY BUFFER
Current MyISAM index space = 231 M
Current key_buffer_size = 7 M
Key cache miss rate is 1 : 83
Key buffer fill ratio = 42.00 %
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
Current sort_buffer_size = 2 M
Current read_rnd_buffer_size = 256 K
Sort buffer seems to be fine
JOINS
Current join_buffer_size = 132.00 K
You have had 1737 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 = 4096 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 3987 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 43471 temp tables, 14% 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 = 128 K
Current table scan ratio = 26 : 1
read_buffer_size seems to be fine
TABLE LOCKING
Current Lock Wait ratio = 1 : 3779
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'.
