I like and use phpjso (http://www.cortex-creations.com/software/phpjso). It can also obfusicate, but if you do that then be sure to use the 'fast decompression' option otherwise you have a initialization lag of up to a full second for +-40Kb of script.

Hi all, I know this has probably been discussed before but I with all the options available, I was wondering what method seems to work best overall for compressing js files. I want to put all my jquery plugins into one file and compress for performance but I'm worried about breaking things. I know there is packer, jsmin etc. Any recommendations.
