I'm also going to be doing a lot of SSL on a Poweredge 2950. So the
above is purely a memory/cpu test correct? (not like doing IO tests
where you want the size of the test data to be at least twice physical
ram). Here's results for the Woodcrest- I assume this is only on a
single core. Yes, I realize that the woodcrest is faster than above
mentioned cpu, but a 100x speed difference? That doesn't seem realistic
to me (although if those are valid results, I'd be pretty happy with
that)...
Well, the Via Padlock has a hardware random-number generator, so the idea was
to test that. It doesn't claim to be fast, just to be truly random
