Which tools do you use to optimize your webapps?
kineticac: For images, I haven't found a better solution than to fire up Photoshop and do batch process on all the images and save for web.  The quality looks the same, and the images are WAY smaller.I've used pngcrush before, but just for png's, and it didn't come close to what Photoshop was giving me as a result.Photoshop does cost ~$700, but if you already have it, definitely give it a whirl.
