mysqld is alive   -- MYSQL PERFORMANCE TUNING PRIMER --  - By: Matthew Montgomery -  MySQL Version 5.0.51a-3ubuntu5.4-log i486  Uptime = 21 days 1 hrs 38 min 49 sec Avg. qps = 3 Total Questions = 7191203 Threads Connected = 2  Server has been running for over 48hrs. It should be safe to follow these recommendations  To find out more information on how each of these runtime variables effects performance visit: http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html Visit http://www.mysql.com/products/enterprise/advisors.html for info about MySQL's Enterprise Monitoring and Advisory Service  SLOW QUERIES The slow query log is enabled. Current long_query_time = 2 sec. You have 899 out of 7191224 that take longer than 2 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 = 8 Current threads_cached = 6 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 = 69 The number of used connections is 69% of the configured maximum. Your max_connections variable seems to be fine.  MEMORY USAGE Max Memory Ever Allocated : 225 M Configured Max Per-thread Buffers : 265 M Configured Max Global Buffers : 42 M Configured Max Memory Limit : 307 M Physical Memory : 1.66 G Max memory limit seem to be within acceptable norms  KEY BUFFER Current MyISAM index space = 5 M Current key_buffer_size = 16 M Key cache miss rate is 1 : 5041 Key buffer fill ratio = 9.00 % Your key_buffer_size seems to be too high. Perhaps you can use these resources elsewhere  QUERY CACHE Query cache is enabled Current query_cache_size = 16 M Current query_cache_used = 6 M Current query_cache_limit = 1 M Current Query cache Memory fill ratio = 39.07 % Current query_cache_min_res_unit = 4 K MySQL won't cache query results that are larger than query_cache_limit in size  SORT OPERATIONS Current sort_buffer_size = 2 M Current read_rnd_buffer_size = 256 K Sort buffer seems to be fine  JOINS Current join_buffer_size = 132.00 K You have had 0 queries where a join could not use an index properly Your joins seem to be using indexes properly  OPEN FILES LIMIT Current open_files_limit = 1024 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 = 120 tables You have a total of 93 tables You have 114 open tables. Current table_cache hit rate is 5%, while 95% of your table cache is in use You should probably increase your table_cache  TEMP TABLES Current max_heap_table_size = 128 M Current tmp_table_size = 128 M Of 292974 temp tables, 87% were created on disk Perhaps you should increase your tmp_table_size and/or max_heap_table_size to reduce the number of disk-based temporary tables Note! BLOB and TEXT columns are not allow in memory tables. If you are using these columns raising these values might not impact your ratio of on disk temp tables.  TABLE SCANS Current read_buffer_size = 128 K Current table scan ratio = 516 : 1 read_buffer_size seems to be fine  TABLE LOCKING Current Lock Wait ratio = 1 : 1280 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'.
