... but breaking font-face in firefox and also can cause java/ajax collision, for example I used rokslideshow + camp26 fisheyemenu and anyhow only one or the other works but not both same time.

Had my site loading very slowly and thanks to this extension and a little tweaking of the options, not only has it drastically improved the speed - it kept my layouts and external components intact! Thank you so much!

My site was loading terribly slow. I installed this plugin and used the default settings and it increased the load speed of my site by at least 60%. Definitely recommended.

Excellent tool, good work !
To "spilios", me too, I have problem with the slideshow (using rockslideshow - images don't appear).
Set the "minify javascript" to "No" and the slideshow will work normally.

Despite best efforts, the default parameters probably won't work for everyone. There are a number of options in the back-end configurations to tune the plugin to your specific requirements.

If you're having problems, please request assistance by submitting a support ticket before reviewing or rating. Thanks.

Excellent plugin. It delivers what it promised and axceeded my expectation. It worked with no problems at all, good documentation, and support. you guys really made a quality product here. Also it has all the parameters so that users can cutomize it for pretty much any custom needs for their site. This is something other plugins did not have

First I wanna say that it does exactly what it says... unless you're using Internet Explorer. I don't, of course. But the majority of my users do. I have a ticker trying to get them to go to Firefox or Opera.
Anyway, when activated, it disrupts the javascript of of some elements. For example, my Joomlaworks "All Videos" and "Tabs and Slides" don't work. When disabled, they work fine. Like I said, this is only in Internet Explorer. In Firefox, Opera, Chrome and Safari, it works fine. I changed each option one by one but it made no difference. The only thing that helped was to disable it.

Unfortunately, because of the existence of Internet Explorer, I had to remove it. Even though I totally hate IE, it's still the most popular browser.

So to sum it up: this is a problem with Internet Explorer and not the plugin's fault. But others I've used are compatible with IE... so I really don't know where the bug lies. Either way, it does what it says in Firefox, so I still give it 5 stars.

This is simply one of the best joomla plugins you can have. Should make any site run significantly faster in just a few minutes set up time. Just make sure to publish it last amongst your system plugins (2nd to last if you are using the cache plugin) to maximize the results.

Definitely put this in the Joomla Core! This thing rocks. No reason not to have this on every Joomla! install.

I tested first time but I don't put much attention to the settings so broke my menu.

I installed again and I played a little with plugin setting ( I exclude from js compress the mootools.js and menu.js) and it work. GREAAAATTTTT.

I must say that i tryed all ather plugins and this is in the end much much better. Tanks.

Before excluding individual files, try experimenting with the various options for positioning the combined JavaScript file.

Very easy to setup. This extension should be a part of the Joomla core; install it with every Joomla installation.

The best extension for js css compression. It is much better than compression using mod_gzip or mod_deflate in apache 1.3/2.2. Must have.

Easy to install and super easy setup.

I selected yes to all the first parameters except for minify HTML and my website climbed 8 points in the firebug page speed tab.

Phoca gallery users: I had a small issue with my modal popup box view on phoca gallery but solved it by adding mootools.js in the "Exclude JavaScript Files box" in the JCH Optimize plugin parameters.

Installs and performs perfectly. Raised a clients score by nearly 10 points. Originally site was just under nearest competitor and now a full 8 speed point ahead.

Terrific job, wish all components worked this well.

I worry about script conflict and am glad this plugin works almost perfectly. Everything works as described. I just have problem getting CK editor to appear in ListBingo.

Together this plugin and smartoptimerz script (and instructions from here: ), my website got a major speed boost.

Thank you.

Better support for editors included in latest release

I was relying on YooTheme's built-in gzip compression but decided to give JCH Optimize a try. Well the results are very impressive. It dropped my average load time from 1.8 seconds to 0.5

So impressed, I just donated to the project.

Thank you. Much appreciated.

Was pretty easy to setup, had to exclude some js/css to get it working. @import support in css would be fab apart from that well worth using!
Owner's reply

@import support now included as of version 1.2.0
