With WinXP Pro, the .Net framework, and the MS Visual complier. Does
anybody have an opinions on which is better two processors or the new hyper
threading thingy? Sort of want things to go a little faster then they are
now.

Thanks,
John
 
Two processors always allows for a full set of complex instruction paths,
but have the overhead of managing them (one processor is the primary and
delegates tasks to the second processor (affinity)). Hyper threading forces
threads to run simultaneously by each using one or more of the complex
instruction paths. There aren't any physical context switches, so things
run a bit faster there, but you still are sharing the instruction paths of
one processor rather than having two separate processors (double the
instruction paths). I am pretty sure my dual proc runs faster than my HT
single proc.
 
Thanks for the response, very enlightening.
