According to Andreas Klemm:

What is your system ? Dual pentium ? Don't forget that 208 is 2.5x 83 MHz
so the whole machine is faster, not the CPU alone.

I have an IBM DORS 32160 narrow (sd0) on ncr0 and a Conner CFP1080S narrow
(sd12) on ncr1. If you have both /usr/src and /usr/obj on the same disk,
you are more I/O bound than I do.

sd0: <IBM DORS-32160 WA6A> type 0 fixed SCSI 2
sd12: <CONNER CFP1080S 3939> type 0 fixed SCSI 2

Even with the "make cleandir" part, I'd be faster than you :-)

Do you mount /usr/obj with async ? noatime ? Both help a lot.

Anyway, I'm really impressed with the K6. Even with bcopy/copyin not using
the FPU, this machine is fast. Last time I did a "make world" on my work
machine (P6/200, 64 MB RAM, 1x Adaptec 7880, 2 disks on it), it was in the
same range (1h20 or so).
