Here's another batch of PPro figures. Now that I finally have three "Real Machines", I can try playing around with FreeBSD a little more. Anyway... FYI... I finally got a working Pentium Pro motherboard and CPU. I had been having some problems with a SuperMicro motherboard. I don't know if it was the motherboard or CPU. On Friday I received an Asus motherboard and 200MHz CPU to replace the faulty ones. It worked perfectly. And here are some relative performance figures: AMD 5x86 133MHz, NICE Super-EISA 486 motherboard, 24MB 60ns RAM, 512K L2 writeback cache, BusLogic BT747s EISA SCSI controller (on a 2GB Barracuda and a 1GB Hawk SCSI drives): Make world(*): ~6 hours, depending on various factors. Intel Pentium 120MHz (**), Asus P/I-P55TP4N (Triton-1) motherboard, 64MB 60ns EDO RAM, 512K L2 pipeline-burst cache, BusLogic BT956c PCI SCSI controller (same drives as above): Make world(*): 3 hours, 10 minutes, totally clean (no pre-built man pages, dependencies, etc.). Intel Pentium Pro 200MHz, Asus P/I-P6NP5 (Natoma) motherboard, 64MB 60ns EDO RAM, 256K L2 P6 cache, BusLogic BT956c PCI SCSI controller (same drives as above): Make world(*): 1 hour, 21 minutes, totally clean (same as above). Wow. A complete clean build of my very bloated kernel (including make clean, config, make depend, make) takes a little over fifteen minutes on my P5/120, and just over seven minutes on my P6/200. Wow. * - My own custom "make world" script that does things in a specific order, and does a few things redundantly. Building the NetBSD-1.2 sources. ** - I have tested it at both 100MHz (33/66MHz bus), and at 120MHz (30/60MHz bus) (20% faster CPU, 10% slower bus). It is just barely faster at 120MHz than at 100MHz, for all the tests I ran, in spite of the slower bus. However, the difference is so small that I can conclude (for my use anyway), that a 150MHz Pentium would be slower than a 133MHz (12.8% faster CPU, 10% slower bus), and a 180MHz Pentium would definitely be slower than a 166MHz (8.4% faster CPU, 10% slower bus). ----------------------------------------------------------------------------- Michael L.
