Uptime = 0 days 23 hrs 3 min 12 sec
Avg. qps = 0
Total Questions = 481
Threads Connected = 2

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

SLOW QUERIES
The slow query log is NOT enabled.
Current long_query_time = 10.000000 sec.
You have 0 out of 502 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 enabled

WORKER THREADS
Current thread_cache_size = 15
Current threads_cached = 0
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 15
Current threads_connected = 2
Historic max_used_connections = 2
The number of used connections is 13% of the configured maximum.
Your max_connections variable seems to be fine.

No InnoDB Support Enabled!

MEMORY USAGE
Max Memory Ever Allocated : 42.11 G
Configured Max Per-thread Buffers : 457 M
Configured Max Global Buffers : 42.05 G
Configured Max Memory Limit : 42.50 G
Physical Memory : 48.97 G
Max memory limit seem to be within acceptable norms

KEY BUFFER
Current MyISAM index space = 117 K
Current key_buffer_size = 32 M
Key cache miss rate is 1 : 43
Key buffer free ratio = 81 %
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 read_rnd_buffer_size = 256 K
Sort buffer seems to be fine

JOINS
/root/tuning-primer.sh: line 402: export: `2097152': not a valid identifier
Current join_buffer_size = 4.00 M
You have had 2 queries where a join could not use an index properly
join_buffer_size >= 4 M
This is not advised
You should enable "log-queries-not-using-indexes"
Then look for non indexed joins in the slow query log.

OPEN FILES LIMIT
Current open_files_limit = 16364 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 = 2048 tables
Current table_definition_cache = 1024 tables
You have a total of 190 tables
You have 199 open tables.
The table_cache value seems to be fine

TEMP TABLES
Current max_heap_table_size = 1.00 G
Current tmp_table_size = 1.00 G
Of 911 temp tables, 12% were created on disk
Created disk tmp tables ratio seems fine

TABLE SCANS
Current read_buffer_size = 8 M
Current table scan ratio = 394808370 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 0 : 688
Your table locking seems to be fine
