Joomla Performance Tip: Investigate Large Database Tables

One of the common bottlenecks on any website, and not just a Joomla website, is large database tables. Large tables, especially those with significant and constant CRUD (Create, Read, Update, and Delete) activities, can cause serious load issues on websites. This means that it’s always a good idea to check your Joomla websites for large tables and see if you can trim them.

For example, if you are using Smart Search, then you will notice that adding/editing Joomla (or K2) articles gets slower and slower with time, and this is caused by the exponential growth of the finder tables (check point #2 here for more information about the harm that is caused by Smart Search).

Another example is the ACYMailing tables, especially those that are used for storing stats. If you are an avid user of ACYMailing, then you probably know what we mean: a load spike when you are sending out emails (because of the new rows added to the ACYMailing stats table), and a load spike when people start opening their emails (all these database updates happening during a relatively short period of time).

Now, the question is, how can you check your database for large tables? Simple! You just go to phpMyAdmin, select the database powering your Joomla website, and then click on the Rows header. This will display the tables sorted by the number of rows descending (e.g. the tables with the most rows will display first). Once you know which tables have the most number of rows, you will be able to formulate a strategy in order to address that (of course, your options are very limited for some tables, such as the #__content table).
