8 Best Plugins for Optimizing WordPress Site Performance

WordPress is one of the best hosting services you will ever find on the web. And, if you are concerned about the effectiveness of this service, you will like 8 best plugins for optimizing WordPress site performance. There is no denying that WordPress sites offer great performance. However, as you start scaling up, you realize that the native tools do not suffice the kind of performance results you are looking for. This is why it becomes necessary to get the third-party support. Thanks to these wonderful plugins, you can enhance the performance of your site instantly.

Speed of your site affects the search engine ranking to a great extent. If the user finds your site slow, he may quickly exit it and move on to the other site. This will increase the bounce rate and hence lower your ranking. You would like to make sure that you are offering best user experience to the visitors. There is a lot you can do with these plugins. For instance, WordPress doesn’t offer cache on its own. But, you can enhance the site performance by going for a plugin that lets you cache various things. Take a look at this list and pick the plugins you like the best.

W3 Total Cache

W3 Total Cache improves the SEO and user experience of your site by increasing website performance, reducing download times via features like content delivery network (CDN) integration.


This free plugin will optimize your WordPress database with the click of a button, or automatically with its built-in scheduler. Redundant information like spam comments, post revisions and other trash items will be cleaned from your mySQL database, speeding up how quickly your site loads.


Autoptimize makes optimizing your site really easy. It concatenates all scripts and styles, minifies and compresses them, adds expires headers, caches them, and moves styles to the page head and can move scripts to the footer. It also minifies the HTML code itself, making your page really lightweight. There are advanced options and an extensive API available to enable you to tailor Autoptimize to each and every site’s specific needs.

P3 (Plugin Performance Profiler)

This plugin creates a profile of your WordPress site’s plugins’ performance by measuring their impact on your site’s load time.  Often times, WordPress sites load slowly because of poorly configured plugins or because there are so many of them. By using the P3 plugin, you can narrow down anything causing slowness on your site.

WP Smush

This plugin compresses images by stripping metadata from JPEG files, optimizing JPEG compression, converting certain GIFs to indexed PNGs and stripping the unused colors from indexed images. You can set it up to automatically compress new images when they’re uploaded to your site.

Lazy Load

Lazy load images to improve page load times. Uses jQuery.sonar to only load an image when it’s visible in the viewport.

This plugin is an amalgamation of code written by the WordPress.com VIP team at Automattic, the TechCrunch 2011 Redesign team, and Jake Goldman (10up LLC).


Imsanity automatically resizes huge image uploads down to a size that is more reasonable for display in browser, yet still more than large enough for typical website use. The plugin is configurable with a max width, height and quality. When a contributor uploads an image that is larger than the configured size, Imsanity will automatically scale it down to the configured size and replace the original image.

WP HTTP Compression

This plugin compresses your pages in the gZip format (if the browser supports compressed pages). HTTP compression can reduce the size of your pages by 60-80%, allowing pages to load three or four times faster.
