WP Parallel Loading System

The WP-PLS (short for Parallel Loading System) is a WordPress plugin that will enhance the loading efficiency of your Blog.

Why use it?

If you have an image intensive Blog, or even if you don’t, this plugin will boost the loading time of your Blog. The more images you have the more it will improve.

The amount of people that will visit your website for the first time or visit with an empty cache or disabled cache is huge, therefore, the best your website performs on that first visit the more chances that person will remain to view your website.

It is also known that nowadays, Google (and other search engines), are taking into account, for ranking purposes, your website page speed. Google Bot does not conserve a cache when it visits your website, so, the faster your website loads the more chances you have to rank higher.

This plug will not change anything on your Blogs Posts. Every change that it makes will be processed in real time, right before the HTML code of your Blog is sent to the browser. There are however some changes needed on a few files, but the plugin will attempt to do everything by himself without causing harm to your files. For every file that he changes a backup is created, therefore, at any time, you can revert the changes back!

How does it work?

Standard HTTP v1.1 requests only allow 2 connections, at the same time, from the same domain.

This plugin will virtualize connections, through defined subdomains. You can have as many subdomains as you like, but I do recommend using a maximum of 5.

Plugin features?

  • Automatic Image Optimization.
  • Parallelize HTTP connections.
  • Page speed improvement.
  • Auto-Path find (Automatically find server root path, sub-domain path, plugin resources path…).
  • Cache loss minimization.
  • Sub-domain real-time health tracking.
  • Auto recovery from resource files bad sync.
  • Ability to activate / deactivate sub-domains
  • Plugin Updates aware. (automatically re-sync files and database after an update)


The plugin is programmed to be aware of this requirements, and if not fulfilled it will not change anything on your Blog. It will not break your Blog code!

  • Your server needs to have a working GD Library module for PHP.
  • You should have a PHP installation with a minimum version of 5.1.3
