Details on "http://now.cs.berkeley.edu/Td/bcopy.html". Okay, finally, the routes came back to life. Your ``P6/Natoma/Intel/server'' was probably a pre production pile of shit. I have a P6 system just getting ready to go to burn in with a 4G quantum Atlas. If you have the time tomorrow I will set it up outside the firewall and let you run benchmarks on it all day long. I think you will find that a current AAI production Pentium PRO 200 system running on the ASUS PCI/I-P6NP5 is quite a blinding fast machine. In this configuration it turns make worlds in about 1:38 minutes, and using multiple spindles it has been seen to go as low as 1:22. All times are 2.1.5 stable with the following /etc/make.conf tweaks: CFLAGS= -O -pipe NOPROFILE= true NOMANCOMPRESS= true SHARED= copies My business has me far to overloaded to run benchmarks for you, but your welcome to come on over and play with the box. I can turn parity off and get another 8 to 12% out of the memory system.... or turn ECC on and slow it down 8 to 12%. Since those require BIOS tweaking it can be arranged for me to do a couple of reboots with tweaks. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation, Inc. Reliable computers for FreeBSD
