Is Linux better than WinNTs

Sometimes I had such problem with switching consoles too, but I donot test it for a new version (it was only tommorow :) ).
First thing I want to test in a new version is a new implementation of posix threads (pthread library). Old pthread have enough problems (but indeed it enough powerfull compare to threads in other systems). Now from a long work have done and we have a new powerfull pthread (like it was reported). On RedHat site there are some features about new system (new kernel features, etc ). I have my own enough big multiprocess/multithreaded program and I want to compare (after rebulding it with a new libs) a performance for new and old systems.
Else there are enough info about internal Linux/Unix/Win features in IBM site and in comparence.

btw: after I take more deep view in a new RedHat system I can of course post my thoughts about it somewhere.

Also it can be a good idea to have a special Linux forum on
Codeguru (because we have a "C++ and Win32API", "Win system" forums, but for Linux/Unix donot have),. May be some later I will try to give this idea to one of moderators (may be Andreas or Gabrial), may be they can help with this.
