Since I didn't run the celeron test myself I have to rely upon the person
who did run it -- he said he did use -j, I just don't know what value he
used. Take it with a grain of salt though, as I can't say for certain he
actually did it because I wasn't watching. On the athlon I did not use
the -j flag for most tests. I did use it once (-j 2 I think) but didn't
notice much of a difference (but it doesn't count because I wasn't timing
the compiles then either).
Just more FYI:
Athlon 500, FIC SD-11 MB, 128 meg PC-100 Micron CAS-2, IDE (not ATA-66)
and
Celeron 400 (2) (overclocked to 520), Abit BP6, 256 meg PC-100 Micron CAS-2,
IDE (not ATA-66)
and for good measure
K6-3 450, ASuS P5A (?? recent SS7 ATX), 256 meg PC-100 Micron CAS-2, IDE
(not ATA-66)
all three systems performed comparably - I ran the tests on the two AMD
systems, the Athlon finished about 25 seconds faster than the k6-3 on the
make bzImage portion. not as much as I had expected, but it was still faster
than the k6-3. i think tom's hardware page has better comparisons of athlons
if that is what your looking for. supposedly smp athlon boards should be
available around January/February (fingers crossed).
[for the record -- my SMP system is an aging Tyan Tahoe II at work].
