What's your all-in-one web resource optimizer?

Question

I'm working with SmartOptimizer: minify js and css, use css data uris, add far expire headers and other features. (http://farhadi.ir/works/smartoptimizer) It works fine, but i don't know if exists a similiar application with similar or best tools (like Google Closure, CSScaffold,..)

If you're not sure witch is better, what's your favourite??

Thanks for reading, sorry for my english

Answer 1

YSlow ( http://developer.yahoo.com/yslow/ ) will tell you where you can optimize, at least, though it won't solve your problems for you.

Answer 2

WEB optimizer(http://webo.name/) is a great thing. It can not only find issues, but also do some optimizing. However it isn't free for commercial use.
