-- For years now, whenever NT has been proven to have some debilitating weakness we've heard from MS advocates that NT would catch up, there was just an incredible faith in this OS and Microsoft's ability to somehow get there. With the recent results of the Linux vs NT serving benchmark that same attitude can be seen in the Linux community. The Linux folks aren't too worried, "Sure the single threaded IP stack was slow but it'll be fixed in the next release.", it's eerily familiar but I have confidence in the Linux community's ability to remedy problems and I don't groan in pain as I used to when Microsoft made similar claims.For advanced 3D graphics Performer + OpenGL based examples and tutors: http://www.dorbie.com/
