Dedicated server only for one medium wp site. I see from mysqltuner get limit like Thread cache hit etc. Access WHM => Restart Services " SQL Server (MySQL) about 5 minutes, other whm menu just 4 sec. -------- Performance Metrics ----------------------------------------------------------------------- [--] Up for: 39m 23s (1M q [765.257 qps], 2K conn, TX: 2G, RX: 204M) [--] Reads / Writes: 99% / 1% [--] Binary logging is disabled [--] Physical Memory : 31.1G [--] Max MySQL memory : 20.9G [--] Other process memory: 0B [--] Total buffers: 19.5G global + 2.9M per thread (500 max threads) [--] P_S Max memory usage: 0B [--] Galera GCache Max memory usage: 0B [OK] Maximum reached memory usage: 19.5G (62.78% of installed RAM) [OK] Maximum possible memory usage: 20.9G (67.26% of installed RAM) [OK] Overall possible memory usage with other process is compatible with memory available [OK] Slow queries: 0% (0/1M) [OK] Highest usage of available connections: 1% (9/500) [OK] Aborted connections: 0.04% (1/2625) [!!] name resolution is active : a reverse name resolution is made for each new connection and can reduce performance [OK] Query cache is disabled by default due to mutex contention on multiprocessor machines.

    MySQL uptime is only 39 minutes??? You can ignore the results. Wait at least 24 hours before running mysqltuner again. Check the database for this website for errors and correct and optimize using phpmyadmin.

    Hi @Naila Did you have a chance to re-run the MySQL Tuner?

See https://dev.mysql.com/doc/internals/en/join-buffer-size.html (specially the conclusions at the bottom of the page). Temporary table size is already large - reduce result set size Reduce your SELECT DISTINCT queries without LIMIT clauses Performance schema should be activated for better diagnostics Variables to adjust: join_buffer_size (> 256.0K, or always use indexes with JOINs) performance_schema = ON enable PFS

    Hello, Per this MySQL had only been up for 9 hours - you need to have it running for at least 24 hours to get accurate suggestions.
    MySQL was started within the last 24 hours - recommendations may be inaccurate
