I am new to multiple cpu's and win3k.
I have an application which performs a batch task. On a 64bit 2400 athlon running 32bit Win3k it uses 100% and performs the task quickly.
On a dual xeon 2.4ghz it only uses 25% cpu usage and takes 4 times as long as the single machine to do the job.
Can somebody please explain why an application that uses 100% cpu on a single cpu machine, only uses 25% of a dual xeon machine?
