Which is why the only valuable test is an empirical one.
haha. My point is that "his word" has no backing because its just theory, and because his fundamentals are wrong. He refuses to grasp the fact that the PCI bus is a burst bus, and that you can't determine the transfer rate or cpu requirement with the A+B=C math that he uses. The number of bursts it takes (and thus # of setups and I/O operations) will vary with traffic levels. As the levels increase, the bursts become shorter, because bus contention increases. So you can't say that the math for transfering 1 packet is the same for 750K packets/second, because its just plain wrong to do so. What do you think "my word" is? My only point was that I use the usage level at which a machine starts dropping packets to determine its point of capacity. I don't see how I can be wrong about anything, since its hard to argue against that point. And what do you think Matt's point was? I don't even think its relevant. > PS. > What's up with your mail-client?
