-- MYSQL PERFORMANCE TUNING PRIMER --
- By: Matthew Montgomery -
MySQL Version 5.1.73-log i386
Uptime = 0 days 3 hrs 56 min 57 sec
Avg. qps = 3
Total Questions = 53971
Threads Connected = 2
Warning: Server has not been running for at least 48hrs.
It may not be safe to use these recommendations

runtime variables effects performance visit:

for info about MySQL's Enterprise Monitoring and Advisory Service
SLOW QUERIES
The slow query log is enabled.
Current long_query_time = 0.100000 sec.
You have 1 out of 53992 that take longer than 0.100000 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
See http://dev.mysql.com/doc/refman/5.1/en/point-in-time-recovery.html
WORKER THREADS
Current thread_cache_size = 16
Current threads_cached = 1
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine
MAX CONNECTIONS
Current max_connections = 100
Current threads_connected = 2
Historic max_used_connections = 3
The number of used connections is 3% 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
INNODB STATUS
Current InnoDB index space = 0 bytes
Current InnoDB data space = 0 bytes
Current InnoDB buffer pool free = 96 %
Current innodb_buffer_pool_size = 8 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
MEMORY USAGE
Max Memory Ever Allocated : 563 M
Configured Max Per-thread Buffers : 131 M
Configured Max Global Buffers : 560 M
Configured Max Memory Limit : 691 M
Physical Memory : 11.70 G
Max memory limit seem to be within acceptable norms
KEY BUFFER
Current MyISAM index space = 670 K
Current key_buffer_size = 500 M
Key cache miss rate is 1 : 91
Key buffer free ratio = 88 %
Your key_buffer_size seems to be fine
QUERY CACHE
Query cache is enabled
Current query_cache_size = 50 M
Current query_cache_used = 4 M
Current query_cache_limit = 1 M
Current Query cache Memory fill ratio = 9.03 %
Current query_cache_min_res_unit = 4 K
Your query_cache_size seems to be too high.
Perhaps you can use these resources elsewhere
MySQL won't cache query results that are larger than query_cache_limit in size
SORT OPERATIONS
Current sort_buffer_size = 256 K
Current read_rnd_buffer_size = 256 K
Sort buffer seems to be fine
JOINS
Current join_buffer_size = 516.00 K
You have had 8 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 = 10110 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_open_cache = 5000 tables
Current table_definition_cache = 3000 tables
You have a total of 116 tables
You have 119 open tables.
The table_cache value seems to be fine
TEMP TABLES
Current max_heap_table_size = 30 M
Current tmp_table_size = 30 M
Of 4537 temp tables, 0% were created on disk
Created disk tmp tables ratio seems fine
TABLE SCANS
Current read_buffer_size = 128 K
Current table scan ratio = 113 : 1
read_buffer_size seems to be fine
TABLE LOCKING
Current Lock Wait ratio = 0 : 54264
Your table locking seems to be fine

General recommendations:
Add skip-innodb to MySQL configuration to disable InnoDB
Run OPTIMIZE TABLE to defragment tables for better performance
