I think that some clients, including the one you use, do not give you
the overall results, but only that of the last completed packet. On an
SMP box this happens to be one of the two running together, so you
have to multiply it by two.
To be sure I am right (or to tell me I'm wrong) compare the output of
the two clients. Do both have a line saying:
"Summary: 35 RC5 packets 0.15:40:08.06 - [1.09 Mkeys/s]"
This line gives the total of both cpu's in the FreeBSD client (which I
am running), while just two lines above it, it reports the speed of
just one CPU: [548,229.19 kkeys/sec]. AFAIK some clients leave out the
summary line, and the one you have is among them.
I cannot imagine that your linux is running so slow. I've used it
myself and it was just as quick or slow as any other OS on the same
box. As far as I can see *all* OS's run at approx. the same speed
with RC5, even Windows.
B.t.w. very nice boxes those Dual PPro. For certain applications, like
RC5, they are faster at 200 MHz than one Pentium II at 350.
