We still know WordPress was originally a blogging platform compact and has been optimized to be less resource accounts as possible. It’s just like that if you are using WordPress blog without install any plugin or theme to time, if you install any plugin that you like and use these themes more complex will make your blog more and become slower.

In this article I would like to introduce the best plugins to speed up your WordPress blog and I recommend you just only need a few of the 8 plugin.

1. WP Super Cache

This plugin generates static html files from your dynamic WordPress blog. After a html file is generated your webserver will serve that file instead of processing the comparatively heavier and more expensive WordPress PHP scripts.

The static html files will be served to the vast majority of your users, but because a user’s details are displayed in the comment form after they leave a comment those requests are handled by the legacy caching engine. Static files are served to:

• Users who are not logged in.
• Users who have not left a comment on your blog.
• Or users who have not viewed a password protected post.

2. Use Google Libraries 

This plugin allows your WordPress site to use the content distribution network side of Google’s AJAX Library API, rather than serving these files from your WordPress install directly.

This provides numerous potential performance benefits:

• increases the chance that a user already has these files cached
• takes load off your server
• uses compressed versions of the libraries (where available)
• Google’s servers are set up to negotiate HTTP compression with the requesting browser

3. Hammy 

Hammy takes your regular content images (within posts and pages) and regenerates a number of smaller sized images. When a person visits your website, it then automatically provides them with the most approriate image (or the smallest one possible). This makes for a better experience, especially on mobile. This uses the new WP 3.5 image code.

4. jsDelivr WordPress CDN Plugin

jsDelivr is a free public CDN that hosts javascript libraries and jQuery plugins, including all of the files they need to work (css/png). It even hosts javascript files that use popular WordPress plugins, like WP SlimStat. Basically if a lot of websites use it then we probably can host it.

With this plugin you can automatically integrate our super fast CDN into your website without the trouble of editing your code and searching for the correct URLs. Just update and then scan your website for files that can be loaded from our CDN.

5. Async Social Sharing

A simple social sharing plugin that loads the third-party scripts asynchronously and after the page loads to improve site performance.

The plugin provides settings to load any of the following sharing widgets:

• Twitter
• Facebook
• Google+
• Linkedin
• Hacker News

6. BJ Lazyload

This plugin replaces all your post images, post thumbnails, gravatar images and content iframes with a placeholder and loads the content as it gets close to enter the browser window when the visitor scrolls the page.

7. 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.

This plugin uses the canvas element for drawing charts and requires requires Firefox, Chrome, Opera, Safari, or IE9 or later. This plugin will not work in IE8 or lower.

8. CloudFlare WordPress Plugin

CloudFlare has developed a plugin for WordPress. By using the CloudFlare WordPress Plugin, you receive:

• Correct IP Address information for comments posted to your site
• Better protection as spammers from your WordPress blog get reported to CloudFlare
