Performance
Table of contents
By default, Tiki is configured with default performance settings which should suit most contexts. For example, Tiki uses the Smarty template engine and it has built-in cache. If you find Tiki slow, this page is here to help.
Basic tips
- Don't be cheap on hardware or hosting. Get the good stuff.
- Turn off any feature you are not using
- Use the Performance Admin Panel at tiki-admin.php?page=performance where you can configure the various performance-related settings, including Content Delivery Network. Otherwise, most performance tuning is done by tweaking the server (outside the scope of Tiki)
- Think also about configuring your web server (for example, setting a long expiry date for images, css and js files)
- Tiki5 has many enhancements related to YSlow tests
- Rename _htaccess to .htaccess to get some of the enhancements provided

MySQL
MySQL has a slow queries feature which is accessible via a log or at the command line. Please read the MySQL manual page to enable this feature.
Using the information in MySQL's chapter on optimization, look for places where indexes may improve the database access speed. Add an index, then re-test. If you think you've found an improved indexing scheme, please open a tracker item on dev.tikiwiki.org.
In tiki-admin.php?page=general, you can activate Log SQL and set Log queries using more than (seconds):
