Faster? I don't know, but I'm getting equal or better crushing from adobe, and great .jpg optimization as well - a 50% jpg saved from photoshop without the optimize function looks kinda yucky, whereas a 50% from ImageReady looks great. I used pngcrusher till I discovered that ImageReady (and this is like the last PPC only version of Photoshop/imageready, before mac came out with Intel Processors, so it runs under Rosetta) does a better job on both the file size and the quality of .png file.
Maybe we're talking about different things? Pngcrush only reduces unneeded data in the PNG file (throws away comments, etc), and tries different compression techniques to encode the exact same data, comparing the resulting sizes. By it's nature there is absolutely no data loss. In referring to 50% and a different quality in appearance between PhotoShop and ImageReady, you seem to indicate you are referring to quality level of the saved file, which is something else.
I'll admit that's pretty good evidence in ImageReady's favor.
