This extension is the best thing to happen to my site since AdminTools. According to Yslow, my site was a laggardly "53" -- but using this extension to minify the CSS and javascript, along with a few other improvements (to .htaccess), I managed to get it all the way to "100"! It's true that all sites and their hosts are different, and some may not get the same stupendous results, but this extension is really brilliant. Also, depending on the template you use, you may not be able to use the "sprites" generation thing to cut down HTTP accesses for images -- the author has a page describing the ins and outs of that. Naturally you should always have a backup before doing anything like this to your site, and it's a good idea to try it out first on a "dev" site -- ideally, on the same host as the live site, so that all server parameters are the same. But this extension can change your site from one that's so slow that surfers leave it before it finishes loading, to one that surfers will hang around and really look at! Both thumbs UP!!

Easy to setup and install. I saw an instant 44% speed increase on the first site I installed this on. This is something I would gladly pay for but free is good too..;)

Got it working perfectly on my Staging server (at Hostgator), but when loaded to the client's server (on PairNetworks) the JavaScript is broken. Submitted a support ticket, but no answer. looks like hardly any tickets are being answered by the developer.
Shame cause it's a good extension, just needs better documentation, server requirements, and better support.
If not for that, would have rated it 5 stars.

I was pleased by the good reviews for this plugin and I thought it would speed up my website a lot after reading them. So I installed it, enabled it and.... then there was blackness and my site suddenly couldn't be found. I tried to go back into the admin area and disable it but I couldn't access any part of my site. Luckily I was saved by logging into my FTP program and deleting the plugin through that.

Be warned, this plugin isn't a gift from the God's to speed up every Joomla website. It has it's flaws and you should carefully consider which optimization extension to use through careful examination of their forums, not just these reviews.

congrats for such a great plugin.. i used to use CSSJSCompress, but when i switched to Joomla 3.0, i found out that the developer didn't update his extension which caused joomla JED to remove it.. i looked around and i found this little gem.. did the same job and minimized load time to about the third of what it was. love it.

New site was taking 14.3 seconds to load. Simply installing JCH dropped it to 5.8 and no CDN and no tweaking of the modules,extensions, etc.
Has done great on a 1.5 site and now on this new 2.5 one.
Highly recommended. Excellent work.

Outstanding! My website was running 4 - 5 seconds, and now it is quite fast. On the Chrome browser, response time is about 1 second, on Firefox about 1 1/2 to 2 seconds until enough appears to be usable. Thanks!!!

Unlike all the other optimizing extensions that we have tried sofar, this one is working very well.
We have been using the CSS & JS concatenation feature for 3 months and we haven't had any problem despite using a lot of cutsom JS, CSS and many extensions.
Thanks for sharing your work!

I have tried almost all plugins listed on JED that are supposed to cache, minify and compress CSS and JS files, but none has worked properly, though I gave myself time to set them, but this one. Almost all option one needs are there. Highly recommend!

Best of it's class, and I say this after trying quite a few plugins that have a similar function. The ability to customize the optimizations is great, however the ability to exclude certain parts as needed is even better. This allows your pages and modules to work where the other plugins would break some functionality.

This plugin is very easy to work with out of the box. I was afraid I would have a number of JS or loading conflicts, but I have not had any. Great plugin!
