WordPress Cache Plugins Speed Test

The time it takes to load the web pages is very important. If some sort of optimization is not done and/or the web host is poor then it could take a very long time to load the website. Due to themes and plugins used along with the web host the results may vary so it’s best to try it out and log results on your own. Below are my results with and without a variety of popular WordPress plugins designed to speed up page loading.

Note: Speed is in seconds unless otherwise noted and size is in kb.

Results using no plugins:

Gtmetrix1.36594095%75%

 

Plugin and Results:

SiteGround Optimizer
SiteGround Optimizer
Developer: SiteGround
Price: Free

Since my website is hosted by SiteGround I figured I’d test their plugin called SG Optimizer which connects with their dynamic cache settings and Memecaching.

Gtmetrix0.96594095%75%
WP Fastest Cache
WP Fastest Cache
Developer: Emre Vona
Price: Free

Next up was the popular plugin, WP Fastest Cache, which I have used in the past since it offers some minify options and caching. It also has CDN support and creates a static version of the website.

W3 Total Cache
W3 Total Cache
Developer: BoldGrid

This plugin is more advanced of the choices presented in this post. It contains many of the same features including minify, caching, CDN, etc but can be finely tuned so this plugin will require more time and testing to achieve the perfect balance of speed and optimization. For my test I activated the plugin and did not change any other settings.

WP Super Cache

Developer: Automattic

Another plugin that has the basics of caching pages and CDN support. Settings are usually pretty simple to configure.

Cache Enabler
Cache Enabler
Developer: KeyCDN
Price: Free

This plugin also contains minifying settings and caching but does not have CDN support which is in a separate plugin by the same developer

Conclusion:

SG Optimizer was what I chose for my website since I’m hosted with SiteGround and it had the best speed. On other hosts, my first choice would be Cache Enabler.
