I recently two make builds.  One a Pentium II /266 and one on a 
PC164SX.  Both used IDE disks.  

The Pii took about 1h40m and PC164SX took 1h10m.  Considering 
the extra amount of work gcc does on alpha, I was pleasently 
surprised by the speed of 21164PC-533 on PC164SX.  (The price
total of 164sx system was < $1500 and 128MB of ECC memory).
