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 Blog. Every change that it makes will be processed in real time, right before the HTML code of your Blog is sent to the browser.

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 recomend using a maximum of 5.

Requirements?

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
  • Access to your server Administration Painel (cPanel, DirectAdmin, Plesk) in order to create new sub-domains for your domain.
    Lets say your domain is wp-pls.com. You will need to create domains like
    image1.wp-pls.com
    image2.wp-pls.com

How to install?

This plugin is installed like any other WordPress plugin out there.

  1. First you need to download it from WordPress Plugin Repository.
  2. Upload the contents of the compacted file to your plugin folder on your WordPress installation.
  3. Go to your WordPress Administration page and activate the Plugin (Plugins → Installed → WP-PLS → Activate)
  4. Go to Settings → Parallel Loading System

Plugin features?

Some of the features that you can expect when using this plugin:

  • 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)

What’s in the cooking pan?

This was only the first release of the plugin. I’ve got a lot of new ideas that I would like to see implemented on next releases.
Some of them are:

  • Also parallelize CSS and JavaScript loading.
  • Add support to also load external images. At the moment it will only load locally stored images.
  • Add real-time rewrite functions to CSS and JavaScript. That way, images that have been called from the CSS file will also be parallelized.
  • Overall improve of the code.
  • Add options to manage image quality rendering.
  • Bug fixes (when found or reported).
  • And much more…

If you have any features that you would like to see implemented, please don’t hesitate to comment this post, tweet me or mail me :)

I need help!

It’s normal if you run into problems and I’m here to tell you how to fix them.

If for any reason the plugin is telling you that it doesn’t have permissions to alter a given file you will need to access your server, using your favorite FTP Client (Filezilla, Cyberduck, FlashFXP…) and change the permissions of the file to 777. You can revert them back to 644 (normal permissions of a file) after the plugin finishes the modifications.

If you get a sub-domain health notification stating that your sub-domain is returning a 500 HTTP error code the most probable explanation is that your sub-domain folder has 777 permissions. Revert them back to 755 and you should be fine.

If you have any further questions please don’t hesitate to send me an email or add a comment on this post.

Creating sub-domains on cPanel?

Creating sub-domains on Plesk?

  1. Log in to Plesk
  2. Once logged in, click the ‘Home’ button in the left navigation frame.
  3. Click on the domain name you wish to create a subdomain for.
  4. Click on the ‘Subdomains’ button. This will take you to the subdomain manager.
  5. Add a new subdomain by clicking the corresponding button (Add New Subdomain).
  6. Enter the subdomain in the associated field. The SSL support checkbox is optional, and should be used if you intend on using SSL with your subdomain.
  7. If you’d like to use the same FTP information as your main domain to access the subdomain, skip down to the ‘Services’ section. If not, select the checkbox ‘Create a separate FTP user account for this subdomain’. Enter an FTP username and password, along with a hard disk quota. If you do not enter a hard disk quota, the subdomain will be allowed to use all resources included with your main domain.
  8. In the ‘Services’ section, it is advised to check all services. This will ensure that your subdomain can support all the features our hosting accounts offer.
  9. Click the ‘OK’ button to create the subdomain.

Creating sub-domains on DirectAdmin?

Creating sub-domains on manually on your server?

To create a sub-domain, if don’t use a Control Panel, edit your http.conf file (normally located on /etc/http/conf/http.conf) and add the following at the end:

NameVirtualHost *:443

<VirtualHost *:80>
ServerName YOUR SUBDOMAIN
DocumentRoot ROOT TO SUBDOMAIN PATH
ErrorLog ROOT TO SUBDOMAIN LOG
</VirtualHost>

<VirtualHost *:443>
ServerName YOUR SUBDOMAIN
DocumentRoot ROOT TO SUBDOMAIN PATH (SSL)
ErrorLog ROOT TO SUBDOMAIN LOG (SSL)
</VirtualHost>

This post will be updated, if needed, to reflect changes made to the plugin.
