This is an ASUS/Triton-I board if it makes any difference. I just upgraded it to a 166. FreeBSD 2.2-GAMMA #10: Fri Feb 21 18:07:37 MST 1997 root@moth.mt.sri.com:/usr/src/sys/compile/MOTH Calibrating clock(s) relative to mc146818A clock ... i586 clock: 165778631 Hz, i 8254 clock: 1193106 Hz CPU: Pentium (165.79-MHz 586-class CPU) Origin = "GenuineIntel" Id = 0x52c Stepping=12 Features=0x1bf real memory = 67108864 (65536K bytes) avail memory = 63631360 (62140K bytes) moth:/sys/compile/MOTH # dd if=/dev/zero of=/dev/null count=1000 bs=1m 1000+0 records in 1000+0 records out 1048576000 bytes transferred in 8.264108 secs (126883142 bytes/sec) Big difference, so it's gotta be related to the CPU speed and not just the CPU class.
