I can't remember the vitals from a full xp install, but the nlited install is undoubtedly faster. Much snappier when using CF and it doesn't take a minute and a half to boot up. Those nLite settings are based on blk02si's from mp3car that I played with (added usb radio support, removed more unused services etc) to better suit my install.
