I belive that I still holds the published record: 21 minutes. Using 130 IBM Valuepoints with 16M and i486DX2/66 on approx 15 ethernets feeding into two Cisco 7010 on an 100Mbit/sec ATM net and landing on 3 Sun SS1000 with filesystems striped over 30 Seagate Elite-2 disks. The slowest part was actually the central farming make process. It seldom managed to hold more than about 75 machines busy at any one time :-) It is interesting that single CPU times are approaching this now, about 30 months later :-) -- Poul-Henning Kamp | phk@FreeBSD.ORG FreeBSD Core-team. http://www.freebsd.org/~phk | phk@login.dknet.dk Private mailbox. whois: [PHK] | phk@tfs.com TRW Financial Systems, Inc.
