[mandana32]

س
wget http://mysqltuner.pl/ -O mysqltuner.pl
perl mysqltuner.pl

تموم شد بعدش از پیشنهاداتی داده استفاده کنین و فایل تنظیمات دیتابیس رو ویرایش کنین

-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    MySQL started within last 24 hours - recommendations may be inaccurate
    Enable the slow query log to troubleshoot bad queries
    Increasing the query_cache size over 128M may reduce performance
    Adjust your join queries to always utilize indexes
    Temporary table size is already large - reduce result set size
    Reduce your SELECT DISTINCT queries without LIMIT clauses
    Increase table_open_cache gradually to avoid file descriptor limits
    Read this before increasing table_open_cache over 64: http://bit.ly/1mi7c4C
    Beware that open_files_limit (10000) variable
    should be greater than table_open_cache ( 100)
Variables to adjust:
    query_cache_size (> 256M) [see warning above]
    join_buffer_size (> 128.0K, or always use indexes with joins)
    table_open_cache (> 100)
    innodb_buffer_pool_size (>= 3G) if possible.
