I've found that 2 40 meg drives can be quite zippy, if you tune them right. You will have to do the installation a couple of times and run something that does a lot of disk I/O (compiling a few big comp.sources.unix distributions) and see what works best for you... change in I/O and CPU speed can change the balance quite a bit. In general, though, putting swap and tmp on different disks helps a lot. > It would seem that sticking the swap space by itself (how much is needed?) With 4 Meg of RAM, 8 Meg of swap was plenty. > you juggle your budget and buy a superfast drive for the critical operations. The EE/CS 11/70 at Berkeley did this, with fixed head drives. 65 users was possible, but pretty slow even for 1980. -- Peter da Silva. `-_-' .
