Do you have a bcache? I just ran this thing on a 600MHz 164lx with a 2mb bcache, 4.3-RELEASE: GCC: cc -O3 -funroll-loops -fexpensive-optimizations -fschedule-insns2 *.c -o tsc.gcc *.o -lcompat Nodes: 627028 Best time: 10408 ms Nodes per second: 60244 tscp> Then I compiled it on an osf/1 alpha and ran it on the same box: DECC: cc -tune ev56 -O4 -fast -ifo *.c -o tsc.deccc Nodes: 627028 Best time: 8904 ms Nodes per second: 70420 tscp> Drew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
