-- MYSQL PERFORMANCE TUNING PRIMER --
- By: Matthew Montgomery -
MySQL Version 5.0.54-log i686
Uptime = 7 days 18 hrs 57 min 34 sec
Avg. qps = 57
Total Questions = 38554678
Threads Connected = 2
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 NOT enabled.
Current long_query_time = 10 sec.
You have 293 out of 38554706 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 enabled
The expire_logs_days is not set.
The mysqld will retain the entire binary log until RESET MASTER or PURGE MASTER LOGS commands are run manually
Setting expire_log_days will allow you to remove old binary logs automatically
See
http://dev.mysql.com/doc/refman/5.0/...ster-logs.html
WORKER THREADS
Current thread_cache_size = 0
Current threads_cached = 0
Current threads_per_sec = 7
Historic threads_per_sec = 7
Threads created per/sec are overrunning threads cached
You should raise thread_cache_size
MAX CONNECTIONS
Current max_connections = 100
Current threads_connected = 3
Historic max_used_connections = 101
The number of used connections is 101% of the configured maximum.
You should raise max_connections
MEMORY USAGE
Max Memory Ever Allocated : 186 M
Configured Max Per-thread Buffers : 158 M
Configured Max Global Buffers : 26 M
Configured Max Memory Limit : 184 M
Physical Memory : 3.93 G
Max memory limit seem to be within acceptable norms
KEY BUFFER
Current MyISAM index space = 536 M
Current key_buffer_size = 16 M
Key cache miss rate is 1 : 87
Key buffer fill ratio = 63.00 %
Your key_buffer_size seems to be fine
QUERY CACHE
Query cache is supported but not enabled
Perhaps you should set the query_cache_size
SORT OPERATIONS
Current sort_buffer_size = 512 K
Current read_rnd_buffer_size = 508 K
Sort buffer seems to be fine
JOINS
Current join_buffer_size = 132.00 K
You have had 2426 queries where a join could not use an index properly
You have had 8 joins without keys that check for key usage after each row
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 = 1024 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 1075 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 1790199 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 = 252 K
Current table scan ratio = 47 : 1
read_buffer_size seems to be fine
TABLE LOCKING
Current Lock Wait ratio = 1 : 491
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'.
