Aren't you the guy running on the nice UltraSPARC with a big cache? ;-)
What really sucks is comparing a P-III with a P-II. Until you fork out
the bucks for the Xenon (and the new motherboard), you're screwed for
server applications that are of any size, as in everything these days.
Even the P-III's L1 cache:
cpu0: Intel Pentium III (Coppermine) (686-class), 733.22 MHz
cpu0: I-cache 16 KB 32b/line 4-way, D-cache 16 KB 32b/line 2-way
cpu0: L2 cache 256 KB 32b/line 8-way
is really not a whole lot better than the P-II, given twice the size on
the latter:
cpu0: Intel Pentium II (Klamath) (686-class), 299.22 MHz
cpu0: I-cache 16 KB 32b/line 4-way, D-cache 16 KB 32b/line 2-way
cpu0: L2 cache 512 KB 32b/line 4-way
(8-way set associativity gives approx. 10% boost in core performance,
but it doesn't really help you hold an overall bigger working set....)
Even a P-Pro is nearly as good, and you can often upgrade it's cache
without replacing the motherboard too!
cpu0: Intel Pentium Pro (686-class), 199.35 MHz
cpu0: I-cache 8 KB 32b/line 4-way, D-cache 8 KB 32b/line 2-way
cpu0: L2 cache 256 KB 32b/line 4-way
Grrrr.... I HATE INTEL!
