![]() ![]() You have the slow log turned on? Let's see the worst query, as indicated by mysqldumpslow -s t or pt-query-digest. We are experiencing very slow performance with queries that use SQLCALCFOUNDROWS within the admin section of WordPress. Also the maintenance of such an index is. In these situations this will help with performance. This may be the case, but there are some godforsaken ugly plugins out there which mean that wpoptions ends up 000s of rows. Here's a head start: tmp-table-size = 32M -> 8M Summary changed from Add index to wpoptions to aid improve performance to Add index to wpoptions to aid/improve performance. Swapping leads to a huge amount of I/O it is better to shrink the settings instead. In a tiny 1GB server that probably includes both WP and MySQL? Change that to 200M. There is one terribly bad setting: innodb-buffer-pool-size = 624M Knowing is half the battle won Acting on that knowledge is where you’ll see the results. How can i optimize the configuation to fix those issues Make sure you have backups of your databases. You should see the confirmation Stopping mysqld: OK. Stop the MySQL service with the command /etc/init.d/mysqld stop. First, establish an SSH connection to your server. Before that could take place, a GPL fork of MySQL was created named MariaDB. To run your existing WordPress scripts with the new RDBMS, start by migrating your existing MySQL database system to MariaDB. MySQL/MariaDB is not always the one which makes a site to work slow. And you might be surprised that SQL queries are the ones which might need to be optimized, and its not a servers side issue. Slow-query-log-file = /var/lib/mysql/mysql-slow.log During the MySQL acquisition of Oracle in 2009 there was a lot of concern amongst the core developers that Oracle would eventually close off MySQL to the world (similar to Oracle’s business model). profiling in MySQL/MariaDB to analyze slow queries Enable a profiler in WP and see how much time does PHP part, SQL part take. Log-error = /var/lib/mysql/mysql-error.log name resolution is active : a reverse name resolution is made for each new connection and can reduce performance Highest usage of available connections: 9% (19/200) Overall possible memory usage with other process exceeded memory In this case, the socket option is probably written in the my.cnf file. The socket file can be in a non-standard path. Maximum possible memory usage: 1.4G (139.86% of installed RAM) Make sure you are using the correct host, port, pipe, socket and protocol options, or alternatively, see Getting, Installing and Upgrading MariaDB, Starting and Stopping MariaDB or Troubleshooting Installation Issues. Here are the results Maximum reached memory usage: 884.8M (89.15% of installed RAM) ![]() I have a server with 2 CPU cores and 1GB of RAM.The server only run one wordpress site.My Server Stack is LEMP.I ran mysql tuner two weeks after setting up the wordpress site. ![]()
