jomCDN - Speed up your Joomla website

Joomla optimization plugin to improve site performance.

A slow loading Joomla site makes nobody happy! It often results in low sales, difficulties to rank high in Google, and other problems. Luckily, improving your Joomla site performance is easier than you think.

One of the quickest ways to speed up your Joomla site is to use a Joomla CDN extension. CDN means “Content Delivery Network” - get the details under the tab “What is CDN?”.

If you make your website visitors happy by improving your website speed, they will thank you with higher conversions and more engagement. Improving the speed of your Joomla website can also help you rank higher in Google - and who doesn’t want that?

How jomCDN helps your visitors

Location-based server load

Thanks to jomCDN, your website content is loaded from your visitor’s nearest server location. Your website will load faster, no matter where they are in the world.

Powerful page caching

When visitors view your web page, their browser will cache your assets (css, images, etc). They will experience nearly instant load time for the next page, as well as the next visit.

Automatic image optimization!

jomCDN includes integration of Yahoo's service. Your images get optimized to the smallest size without losing any quality! No visible difference for your website visitor, but a big improvement in the page load speed!

Best of all: you don't have to do a thing, it is all automated!

How jomCDN helps you

Better server performance

By using jomCDN you save money on bandwidth, and can sustain high traffic periods much better. Your CSS and javascript files are automatically compressed and minified - reducing your bandwidth with up to 80%! Add to this the automatic optimization of your images, and you'll save even more!

Higher conversion rates

Research shows that a slow loading website will lose visitors.

If visitors equal sales for your website, you can't afford to lose a single one! When pages load faster, visitors stay longer and are more likely to convert to customers.

In a study, Akamai revealed that the new threshold for ecommerce sites is 2 seconds. That means if a visitor does not see your page within 2 seconds, they're likely to leave! Don't risk it - get jomCDN now!

What others say

We know that jomCDN will help you improve the speed of your Joomla site, but don't just take our word for it - read some of our customers’ testimonial on the Joomla! Extension Directory:

“My website's Google Pagespeed rating went from 67 to 86, which is remarkable.” A solid product with excellent support

”I’ve used JomCDN on a few sites now (configured with Amazon S3 and Cloudfront.) Installation sounds complicated at first, but if you follow the instructions step-by-step you'll be fine. I had a small problem on one site, and the support was excellent; corePHP adjusted a setting and then everything worked perfectly.

Most importantly, it does what it says - it has dramatically improved the load time of each site I've installed it on!” A must-have for any Joomla site

“It really helped my site to load twice as fast as before and I even moved up on my google ranking. This was a great purchase. Thanks.” Great product

“I took a chance on JomCDN and it immediately cut my homepage load time from around 4.5 seconds to around 2.5 seconds. Two seconds makes a tremendous difference in terms of whether a person will stay on your site or move on to the next Google hit!

With additional tweaking, I've gotten the site down to the one second range, almost as fast as Google or Yahoo's home page! Who says Joomla can't be used for professional-quality sites!!!” JomCDN is a must-have in my opinion

What is a CDN

Let your visitors access your Joomla website faster

Imagine the Internet as a bunch of computers all over the world. Each computer store the website data that you see when you browse the web.

If the website you visit is stored on a computer on the other side of the world, it will take longer to load on your computer.

CDN means “Content Delivery Network” (or content distribution network). It’s also a system of computers around the world, but they contain copies of the website data. Keep on reading, and you'll understand why this is useful for your Joomla website.

Why should you use a Content Delivery Network (CDN)

Nobody likes a slow loading website! Your website visitors might even leave your site before it loads. When you use a CDN extension for your Joomla website it changes everything!

By using a content delivery network (CDN), your website visitors will access the copy of your website data that is nearest to them - instead of pulling it directly from your central server.

This means faster loading and happier website visitors - and no more visitors leaving your Joomla website because it’s slow!

Joomla website speed and SEO

One of the most important factors in technical SEO today is page speed. When you use a Joomla CDN extension:

  • your Joomla website will load faster
  • you will follow Google’s guidelines for performance optimization
  • you improve your chances of ranking higher in the search engine results

If you want to increase your chances of higher rankings and happier visitors (more likely to convert to customers) - get jomCDN now!
