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

SLOW QUERIES
Current long_query_time = 10 sec.
You have 3 out of 369639 that take longer than 10 sec. to complete
The slow query log is NOT enabled.
Your long_query_time may be too high, I typically set this under 5 sec.

WORKER THREADS
Current thread_cache_size = 384
Current threads_cached = 21
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 500
Current threads_connected = 8
Historic max_used_connections = 25
The number of used connections is 5% 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

MEMORY USAGE
Max Memory Ever Allocated : 264 M
Configured Max Per-thread Buffers : 2 G
Configured Max Global Buffers : 154 M
Configured Max Memory Limit : 2 G
Physical Memory : 3.95 G
Max memory limit seem to be within acceptable norms

KEY BUFFER
Current MyISAM index space = 825 M
Current key_buffer_size = 16 M
Key cache miss rate is 1 : 275
Key buffer fill ratio = 100.00 %
You could increase key_buffer_size
It is safe to raise this up to 1/4 of total system memory;
assuming this is a dedicated database server.

QUERY CACHE
Query cache is enabled
Current query_cache_size = 128 M
Current query_cache_used = 36 M
Current query_cache_limit = 1 M
Current Query cache Memory fill ratio = 28.47 %
Current query_cache_min_res_unit = 4 K
Query Cache is 16 % fragmented
Run "FLUSH QUERY CACHE" periodically to defragment the query cache memory
If you have many small queries lower 'query_cache_min_res_unit' to reduce fragmentation.
MySQL won't cache query results that are larger than query_cache_limit in 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 = 1.00 M
You have had 9 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 = 4110 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 = 1800 tables
You have a total of 338 tables
You have 396 open tables.
The table_cache value seems to be fine

TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 64 M
Of 13933 temp tables, 3% 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 = 1020 K
Current table scan ratio = 1417 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 176
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'

max_connections = 300

key_buffer = 256M
query_cache_type = 1

query_cache_limit = 4M
table_cache = 5000
low_priority_updates = 1
