I've got an FX-51 that I initially loaded 32-bit SUSE on (this was before SUSE supported SATA drives right out of the box) and was pleasantly surprised at how fast the 32-bit programs ran (chess engines included). When I finally installed the 64-bit version, I was unpleasantly surprised at how *slow* the 32-bit software ran (including and especially the various Linux engines I test against). I got the requiste 64-bit boost when I converted Djinn over to a true 64-bit program but was somewhat dismayed with the 32-bit slowdown of its sparring partners. I *could* dual-boot into a 32-bit version of Linux for testing but frankly that offends my sensibilities and seems like a bit of a waste. regards, --tom
