- Combine background images in a sprite
- Minify (Compress) and gzip aggregated files
- Exclude individual files or files from extensions that do not aggregate well
- Fixed PHP warnings when either Combine Js/CSS is disabled
- Add ability to add items to multi-select exclude options
- Improved support for popular editors
- Significantly improved the 'Optimize CSS Delivery' option
- If 'url rewriting' is set on auto (default), plugin will detect support and automatically select Yes or No so this check is not made on every download
- Scripts with 'document.write' will only be excluded by default if they are in the body of the page.
- Other minor improvements
I tried enabling every option.. I use Yoothemes, Rocketthemes, etc and the only thing I had to turn off where the CSS Sprites in one of my Yoothemes, but my load time was still dramatically reduced. Can't wait to apply this to the rest of my sites. Thanks!
+ Installation: just use joomla installer
+ Configuration: there are 20+ options, but don't be scared - most are on/off options, with explanations that any joomla administrator will understand.
+ Speed gain: tested my site with 5 different web page analysis tool: after installing this plugin all showed *at least moderate* gain in page speed. In my case both number of CSS and Script files was reduced, also CSS and scipt size. Total bytes loaded was cut 30% with my site. Most importantly this plugin seemed to get rid of ALL css-derived images (mostly from typography) that were not needed on the tested page. Result: http requests were cut down 90%!
Did not find any Cons really. So no reason why You sholdn't give it a try.
It is a pity, however, that the sprite generator does not seem to be working.
Nevertheless, I wholeheartedly recommend this plugin.
The sprite generator did not work well for me on my site. It only found a single image and that image ended up having black artefacts in it.
A feature I would like to see added is a "Development" mode that shows you what actions were taken, what the compression values were including percentage saving. The JFinalizer plugin has this capability and it is really easy to tell whether things are working and what they are doing.
I spent the day testing out all of the minifier plugins/extensions listed here and this was the ONLY one that pruduced results worthy of any note. The main goal for my client was to reduce the load time of their page. Using JCH Optimize reduced the page load time by a staggering 50% :)
JCH is a breeze to set up, has plenty of options (even for the advanced user) and so far I can't fault it.
As usual with performance optimization, it pays to take some time to work with the plugin. Out of the box it will give some improvements. But the biggest gains are seen from setting other options, and making the small, site specific changes to ensure everything still runs smoothly.
With everything configured, big jumps in PageSpeed and YSlow scores are easy to see over unoptimized sites. And of course, precious seconds off your measured real-world download speeds.
Consider setting this one up on any production Joomla site. It is unglamorous, but there aren't many things you can do with half an hour that will make such a worthwhile difference in the long run.
