32-bit vs. 64-bit SMP clients?

[uncle_fungus]

I can't say which distribution is "best" but if you go with Ubuntu, use 8.04.1 rather than 8.10 as the SMP client will produce roughly 30-40% more PPD on 8.04.1. At least that's my experience and I've seen others report the same especially on 4 or more cores.

Where is there such a huge difference between Ubuntu 8.04 and 8.10 with the SMP client???

The 2.6.27 kernel which came with 8.10 initially had a significant performance impact on FAH. The 2.6.28 kernel has been reported to fix whatever was "broken" in the .27 kernel.

Hmm....interesting.

And I am guessing that the default 8.10 doesn't have the updated kernel in it?

I think that I might be about ready to start testing the Linux SMP client now on SLES10 (possibly 9, don't know yet for sure), CentOS, and Ubuntu (not sure which version/variant yet.)
