I tried it on my machine, the following from dmesg Timecounter "i8254" frequency 1193182 Hz CPU: Pentium II/Pentium II Xeon/Celeron (300.68-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0x651 Stepping = 1 Features=0x183f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR> real memory = 100663296 (98304K bytes) One comment is that the test program needs to be compiled as a C++ program. I doubt that's significant, but ... Here are my results $ time ./a.out delta: 5s 43662us 5.06s real 0.64s user 4.40s system I know the machines aren't really comparable, but since mine's about million times slower than the submitter's machine and it ran in the about the same time his did ... I've got a spare partition, I'll try to load 4.2 and try it there as well tonight. joe To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-standards" in the body of the message
