Yo,
Just curious, have many people got good performance gains from
multithreading in 5.5? I'm on a single processor (drat!).
Anyone like to share their findings - how much improvement, how many
processors, what kind of programs? What platforms?
Cheers,
T.

Yo, don't bother with a detailed test - I wasn't looking for small
margins. One might have expected multiples rather than fractions.
My own code's got this big, fat WHERE statement that would probably be
just the right application. And loads of matrix operations too... Ah,
but not sparse ones I see, back to the drawing board...
Ciao.
