-- MYSQL PERFORMANCE TUNING PRIMER --
- By: Matthew Montgomery -
MySQL Version 4.1.22-standard-log i686
Uptime = 2 days 8 hrs 34 min 5 sec
Avg. qps = 31
Total Questions = 6385543
Threads Connected = 5
Server has been running for over 48hrs.
It should be safe to follow these recommendations

SLOW QUERIES
Current long_query_time = 3 sec.
You have 10072 out of 6385581 that take longer than 3 sec. to complete
The slow query log is enabled.
Your long_query_time seems to be fine
WORKER THREADS
Current thread_cache_size = 0
Current threads_cached = 0
Current threads_per_sec = 5
Historic threads_per_sec = 3
Threads created per/sec are overrunning threads cached
You should raise thread_cache_size
MAX CONNECTIONS
Current max_connections = 500
Current threads_connected = 5
Historic max_used_connections = 242
The number of used connections is 48% of the configured maximum.
Your max_connections variable seems to be fine.
MEMORY USAGE
Max Memory Ever Allocated : 668 M
Configured Max Per-thread Buffers : 1 G
Configured Max Global Buffers : 17 M
Configured Max Memory Limit : 1 G
Physical Memory : 1.97 G
Max memory limit seem to be within acceptable norms
KEY BUFFER
Current MyISAM index space = 228 M
Current key_buffer_size = 7 M
Key cache miss rate is 1 : 66
Key buffer fill ratio = 57.00 %
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 = 2 M
Current record/read_rnd_buffer_size = 256 K
Sort buffer seems to be fine
JOINS
Current join_buffer_size = 132.00 K
You have had 377 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 = 2500 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 829 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 127718 temp tables, 15% 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 = 56 : 1
read_buffer_size seems to be fine
TABLE LOCKING
Current Lock Wait ratio = 1 : 324
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'
