people think this is Nope, I routinly run with 80MB swap (here
and at home.) And it's a difficult question, because there are
tradeoffs: Either you want one bzip to run fast, or you want a
dozen bzip par. run with high troughput. (That's nicely
demonstrated by EIDE/SCSI on a multiuser server: Replacing a 5
yrs old SCSI disc with a new EIDE that was in benchmarks 3-4
times faster resulted in grinding teh server to a halt. I had to
replace EIDE disc with a new SCSI disc, which again in
benchmarks is about 50-60% of the speed of the EIDE disc, but I
can do background kernel recompiles without anyone even noticing
:) ).  > needed, well I can tell you, it isn't. A year ago, I
