  2. MySQL Configuration
  3. WordPress Plugin
  4. Your Theme

  1. Always try to use as minimum plugin as possible.
  2. Before installing or using the plugin, read the plugin review on internet
  3. Always test the website performance after and before the plugin installation.
  4. Always upgrade your plugin to latest version.

Theme Optimization

If you are getting bad result in gtmetrix for your wordpress website then most of the time it is due to your theme. So be careful before choosing your theme. You can follow following step to evaluate your theme performace before installing the theme and using it

  1. Always use the theme for which demo URL is available.
  2. Check the demo URL in gtmetrix. If Demo URL has good speed rank then maximum probability that theme is good.

Cache Setup

Last but not least! You should always setup caching of your website. I must say that the biggest point in your WordPress Performance Tuning is how efficient is your website cache. For your WordPress performance tuning you can setup following type of cache:

  1. Fragment Cache:  Fragment cache is technique to cache particular section of page. This help to reduce the process burden and you will get the better page load time. Plugin like W3 Total Cache and Fragementcache.
  2. Browser Cache: There are some plugin which can set the browser cache. Mainly they generate .htaccess rule so that your static file like image and media will be served by W3Total Cache.
  3. Page Cache : Some plugin can cache your wordpress page. They basically generate HTML of your complete page and save it. On every request they check if page is generated then they serve that HTML page. It saves lots of processing time. There are some plugin which can provide you page cache. Best one is W3Total Cache.
  4. Content Delivery Network: If your website is really very high traffic website then you should use content delivery network(CDN). CDN fetch the page from your website and save it on different location. Also it deliver the page to user from their own location. So load on your web server get reduced dramatically. Also CDN are highly optimized.
