Kod:
SLOW QUERIES
Current long_query_time = 10 sec.
You have 2410 out of 4285166 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 = 128
Current threads_cached = 121
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 = 108
Historic max_used_connections = 266
The number of used connections is 53% of the configured maximum.
Your max_connections variable seems to be fine.
MEMORY USAGE
Max Memory Ever Allocated : 884 M
Configured Max Per-thread Buffers : 1 G
Configured Max Global Buffers : 170 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 = 128 M
Key cache miss rate is 1 : 2696
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 = 32 M
Current query_cache_used = 25 M
Current query_cache_limit = 4 M
Current Query cache Memory fill ratio = 80.26 %
Current query_cache_min_res_unit = 4 K
Query Cache is 15 % 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.
However, 39377 queries have been removed from the query cache due to lack of memory
Perhaps you should raise query_cache_size
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 = 132.00 K
You have had 122 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 = 4510 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 = 2000 tables
You have a total of 883 tables
You have 1996 open tables.
Current table_cache hit rate is 69%, while 99% 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 73333 temp tables, 17% 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 = 1877 : 1
read_buffer_size seems to be fine
TABLE LOCKING
Current Lock Wait ratio = 1 : 542
You may benefit from selective use of InnoDB.
