-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    MySQL started within last 24 hours - recommendations may be inaccurate
    Adjust your join queries to always utilize indexes
Variables to adjust:
    join_buffer_size (> 1.0M, or always use indexes with joins)

        -- MYSQL PERFORMANCE TUNING PRIMER --
             - By: Matthew Montgomery -

MySQL Version 5.1.65-cll i686

Uptime = 0 days 0 hrs 7 min 6 sec
Avg. qps = 108
Total Questions = 46268
Threads Connected = 14

Warning: Server has not been running for at least 48hrs.
It may not be safe to use these recommendations

runtime variables effects performance visit:

SLOW QUERIES
The slow query log is enabled.
Current long_query_time = 10.000000 sec.
You have 1 out of 46291 that take longer than 10.000000 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
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 = 12
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 = 15
Historic max_used_connections = 40
The number of used connections is 40% of the configured maximum.
Your max_connections variable seems to be fine.

INNODB STATUS
Current InnoDB index space = 592 K
Current InnoDB data space = 432 K
Current InnoDB buffer pool free = 99 %
Current innodb_buffer_pool_size = 350 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 : 1017 M
Configured Max Per-thread Buffers : 943 M
Configured Max Global Buffers : 640 M
Configured Max Memory Limit : 1.54 G
Physical Memory : 2.00 G
Max memory limit seem to be within acceptable norms

KEY BUFFER
Current MyISAM index space = 148 M
Current key_buffer_size = 256 M
Key cache miss rate is 1 : 479
Key buffer free ratio = 85 %
Your key_buffer_size seems to be fine

QUERY CACHE
Query cache is enabled
Current query_cache_size = 32 M
Current query_cache_used = 2 M
Current query_cache_limit = 16 M
Current Query cache Memory fill ratio = 8.29 %
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 = 4 M
Current read_rnd_buffer_size = 256 K
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 1.00 M
You have had 375 queries where a join could not use an index properly
You have had 2 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 = 8302 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 = 4096 tables
Current table_definition_cache = 1024 tables
You have a total of 987 tables
You have 1036 open tables.
The table_cache value seems to be fine

TEMP TABLES
Current max_heap_table_size = 64 M
Current tmp_table_size = 64 M
Of 966 temp tables, 7% were created on disk
Created disk tmp tables ratio seems fine

TABLE SCANS
Current read_buffer_size = 4 M
Current table scan ratio = 60739 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 74
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'.
