I am running this site: on Wordpress.

Recently I came across a plugin that claims to increase the page load efficiency of my site. the plugin details can be found here:

Now the plugin mentions a self-hosted method for CDN which is known as pipelining. It states:

If you do not have a CDN provider, you can still improve your site's performance using the "Self-hosted" method. On your own server, create a subdomain and matching DNS Zone record; e.g. and configure FTP options on the "Content Delivery Network" tab accordingly. Be sure to FTP upload the appropriate files, using the available upload buttons.

Now I have created a sub-domain but I don't know how to enter matching DNS Zone record and configure FTP options.

Please guide me in this regard. I went to my cPanel -> Simple DNS Zone Editor. It contains:

Add an A Record


Add a CNAME Record


What am I supposed to enter in this??

+1 for W3TC plugin - it's not for the feint-hearted, but the results are pretty amazing if you get it set-up right. –  Mike Hudson Sep 17 '11 at 11:43

Pipelining, or using a cookie-free subdomain to enable concurrent downloads of static/cached items (like CSS/JS) is a really good idea.

You didn't actually have to create a sub-domain to enable this approach (but there's nothing wrong about doing such), all you needed to do was create a CNAME record for and ensure this "points" to your, so to answer your question:


You don't need to add anything to the A Record box.

There's a few other good tips in the last link (e.g. ensuring cookies aren't accidentally set using Google Analytics, and some other WordPress specific stuff.)
