Go up one level in this thread

With all due respect to Ernst and Dann, I think they're wrong.

Context switches will hurt your program, but not very much.

If you use clock() in Linux to time your program, you will [almost] always get
exactly the same numbers, regardless of what else the computer is doing.

I think NT is not designed to keep track of how much time each process uses, so
it would be impossible for an NT clock() function to work correctly. I don't
know what it returns, but I'm pretty sure that it isn't the elapsed time for the
process.
