- As even ardent VAXers will admit, the VAX CPU is no great shakes in
- terms of raw CPU power. But it has excellent I/O handling which is
- *very* necesssary when your are handling 25+ users on a 8600. The
- 486/33 will handily outperform most of the VAX 8xxx series in terms
- of MIPS, but an ISA box can never handle 25 users. The bus is going
- to be a *reeeaaall* bottleneck. EISA would help much, but even then
- a PC doesn't have dedicated I/O channels etc. that a VAX mini has.
-
- Now if you were comparing a 486/33 EISA with bus-mastering 32-bit
- peripheral cards and a pre-4000 VAXStation, the I/O performance
- would be lot closer.
-
- But your point is valid. Linux is not a resource hog. And with
- shared libs X is more manageable. On an 8 meg machine with 2 xterms
- and 1 X11Emacs, It doesn't swap much at all during a kernel compile.
- `free' said that only 280 odd KB of swap was being used.
