What is the basis for this advice?
Is 2.0.x SMP just a crappy performer because it doesn't have granular
I'm using 2.1.x on my Alpha box and it seems stable. I'm a little
hesitant to run it on a production machine, but I can give it a shot.
With the kernel issue out of the way, I'm still not sure whether SMP
is the better solution.
