I had a NexGen P90 prior to this PPro-166. The NexGen crunched the Bovine RC5-56 client at about 90k keys/sec. This PPro-166/512k is currently doing 420k. But a couple of days ago I upgraded to the 11/11/97 Bovine client and got several days of 460k keys/sec until I got the great idea to update my late October 2.2.5 kernel. Am back to 420k keys/sec. Don't know what it was, the old kernel doesn't run faster any more. Possibly I got the caches loaded just right or something? Maybe I hit a series of easy to crunch keys? The NexGen did "build world" in the 7 to 9 hour range. Moving the exact same memory, HD, 2940, video card, case and PS to the PPro yeilds 2:45 with sync mount, 2:15 async. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
