Is there a Magento extension for combining/compressing javascript and css?

I thought Magento came with this feature out of the box but it doesn't appear to be working at all. I'm not sure if I haven't set it up properly, but right now I'm resorting to using cat and altering the page.xml layout file to use the combined javascript and css files.

Can I make Magento do this inste开发者_StackOverflow社区ad or is there an extension that adds this feature?

Go to System>Configuration>Developer and alter the settings in the Javascript and CSS settings boxes. Ensure that you have correct Configuration Scope set in the top-left of the page for your website/store.

Make sure that you flush the cache after changing the setting.

P.S. The Fooman Speedster extension will also perform this task.

There is also mod_pagespeed which does this for all output from your server but doesn't hurt Magento while it does it.

There are extensions in Magento Connect like JS/CSS Compression minify or on the web like Compressor.

this extension works fine and has improved our site's performances to a considerably higher levels...

Think this might help someone...

install mod_pagespeed by google on server zero configuration for your magento.
