What's wrong Danial, now that you have actually had to think about it, now realizing you have some holes in your bitching? Scared that I'm about ready to start punching holes in your flimsy inferences? Danial, you spewed some accusations about the core team making FreeBSD's network performance slower in the newer versions. As I said before, you haven't posted anything to back this up. I know you think your misunderstood but you fail to realize we all understand what your bitching about very well, and are waiting for you to put your money where your mouth is and start posting some repeatable tests. Until then, your just puffing air. And that goes for the rest of you claiming that the later versions of FreeBSD's network performance are better. You too are puffing air. Start showing some test results or go away. Ted
