Here’s sort of a part 2 to our previous “Speed up your WordPress site” post. Admittedly, it’s not quite your own CDN (Content Delivery Network) but the idea is similar: automatically copy data to other virtual server URLs so your page data can load in parallel. How could one do this? There’s a plugin for that – it’s called WP Parallel Loading System. According to the plugin author, your browser will only allow 2 concurrent connections from the same URL on a page. This plugin will off load data to a new URL that you’ve setup and should re-code your pages to automatically pull the content from there.
You’ll need to be versed in your web host company’s control panel (like cPanel or Plesk) to setup virtual sub-domains but other than that it seems pretty straight forward. Theoretically if you have accounts at other web hosting provider, you could have sub-domains setup there too. Anyone tried this and any good (or bad) results?
