Hello list,

I've recently recompiled a program to use ngpt instead of LinuxThreads, with 
no changes to the source. The performance of my app dropped from 4kHz down 
to about 3kHz. Admittedly, I don't have kernel support for ngpt yet (I'm 
using an unpatched 2.4.17) and the test box was a uniprocessor, but I would 
not expect performance to drop by 25%. Is this even a fair test?

Is there any reason to believe that performance would *much* better with M:N 
threading on an SMP machine, or should I stick to LinuxThreads?

Thanks,

Don Dade
