The purpose of this plugin is to minimize page load time and resource usage by updating the page title and content only rather then reloading the entire webpage. 
The new contents and titles are fetched by ajax calls.
Restriction: 
As the rest of the page like header including all styles and scripts, footer and sidebars are not affected, you should only use this to switch between pages with the same overall layout and requirements.
You can enter shortcodes in the page content that will show up as a button or a text link. 
When activating the link, the pages title and content will be replaced by the title and content of the specified page.
There are four possible independant arguments to the shortcode: 
– page (required). This can be the page title or the page id. 
– text (optional). The button text or textlink text. 
– title-elm (optional). The title element id or class if it is not the default as entered on the settings page. 
– content-elm (optional). The content element id or class if not default.
Examples: [pla page=”Tet page”] [pla page=”5″ text=”Go to the testpage”] [pla page=”My Page” content-elm=”#my-div”]

Page Load Ajax

This plugin enables the use of shortcodes that create links to replace the current page content with the content of another page.

About 0.5 seconds faster page load of the site, even after you’ve taken the various means for faster site, without making any changes.
Google and Amazon have shown, there is a huge value to 0.1 seconds to shorten further after you have improved to about 1 second load time of the page. pjax and preload provides about 0.5 seconds of this value.
You can see if was how fast this plugin from the output of the console.
<pre>
[-310, 1, 361, 379, 403, 424, 450, 486, 487, 491] 
["preload(-310)", "continue(1)", "load(361)", "parse(379)", "head(403)", "content(424)", "css(450)", "script(486)", "renderd(487)", "defer(491)"]
</pre>
If you have problems reading such as JavaScript and CSS, it is necessary to set the pjax of built-in <code>load.reload</code> and <code>load.ignore</code> parameter.
This plug-in is like a trial version. If you want to optimize and customize in more detail, it is recommended that you set directly jQuery plug-ins built without the use of this plug-in.

Preload & Pjax Faster Page Load

Can't go wrong with this plugin if you are just posting text and images on your blog. I really like using this plugin, or Flying Pages by WP Speed Matters... can't go wrong with either of them.

Vroom vroom!
