What's the clock speed of the processor? Those 1193182 Hz
is the hardware timer rate, not the processor clock rate.
I don't think intel ever made 486's with 1.2 MHz. ;-)

That's probably because there's not enough RAM. With only
12 Mbyte, it has to swap quite a bit during make world.
Put a bit more RAM into it, and it will be considerably
faster.
I once did a make world on a 486DX-33 with 32 Mbyte RAM.
Both /usr/obj and /usr/src were mounted via NFS (!) via
Ethernet (10 Mbps), because the box didn't have enough
local diskspace.
It took "only" 28 hours.

Yep, probably because of swapping. Poor box. :-)
Only 4.6% spent for actual compilation -- a sure sign of
a misconfiguration (not enough RAM).
