-------- General Statistics --------------------------------------------------
[--] Skipped version check for MySQLTuner script
[OK] Currently running supported MySQL version 5.0.75-0ubuntu10.2-log
[!!] Switch to 64-bit OS - MySQL cannot currently use all of your RAM
-------- Storage Engine Statistics -------------------------------------------
[--] Status: +Archive -BDB -Federated +InnoDB -ISAM -NDBCluster
[--] Data in MyISAM tables: 8M (Tables: 158)
[--] Data in InnoDB tables: 26M (Tables: 31)
[!!] Total fragmented tables: 7
-------- Performance Metrics -------------------------------------------------
[--] Up for: 9h 11m 8s (1M q [37.617 qps], 7K conn, TX: 1B, RX: 149M)
[--] Reads / Writes: 10% / 90%
[--] Total buffers: 2.2G global + 30.1M per thread (150 max threads)
[!!] Allocating > 2GB RAM on 32-bit systems can cause system instability
[!!] Maximum possible memory usage: 6.7G (189% of installed RAM)
[OK] Slow queries: 0% (8/1M)
[OK] Highest usage of available connections: 6% (9/150)
[OK] Key buffer size / total MyISAM indexes: 300.0M/16.0M
[OK] Key buffer hit rate: 99.3% (384K cached / 2K reads)
[OK] Query cache efficiency: 32.4% (58K cached / 180K selects)
[OK] Query cache prunes per day: 0
[OK] Sorts requiring temporary tables: 0% (0 temp sorts / 20K sorts)
[!!] Temporary tables created on disk: 37% (7K on disk / 19K total)
[OK] Thread cache hit rate: 99% (9 created / 7K connections)
[OK] Table cache hit rate: 50% (390 open / 771 opened)
[OK] Open file limit used: 9% (501/5K)
[OK] Table locks acquired immediately: 99% (1M immediate / 1M locks)
[OK] InnoDB data size / buffer pool: 26.7M/800.0M
-------- Recommendations -----------------------------------------------------
General recommendations:
Run OPTIMIZE TABLE to defragment tables for better performance
MySQL started within last 24 hours - recommendations may be inaccurate
Temporary table size is already large - reduce result set size
Reduce your SELECT DISTINCT queries without LIMIT clauses
What should I do?
