It's the kernel Hz, not FPS. The kernel Hz i beleive is involved with how quickly the system timer polls the interrupts? I'm not totally sure on the technicalities of it, so i'm just making vaguely-educated guesses. With 100HZ, there is a 10ms delay before an application can grab a slice of CPU time, or before any I/O action can happen? With just one or two real-time processes on a box, this isn't too bad, but as soon as you get past that, there will be huge problems with servers fighting for CPU time.
Thus a server having 1000 *HZ*, not FPS, does mean a lot to the client, and even more to the host. There's no way that you can get the most out of your hardware in terms of server processes on one physical piece of hardware without pusing the HZ as far as it will go, as most gaming engines are too sensitive and are made so that the results of failing to have a slice of CPU time when it's needed can be fairly catastrophic in terms of performance for clients. Really the main thing is that before the frames are sent out by the server to the client (here I agree - anything more than 120 fps is a bit silly in terms of actual frames going down a wire), all the calculations have to be done also! So how on earth is the server going to manage to make the correct calculations and put together the frames, regardless of sending them out to clients at anything more than 50fps without modifying the HZ, or another similar setting, which is why the kernel HZ is modified. I actually laughed out loud when I saw the snip before I saw these replies. I found it funny at least :-) Chris Adams ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, August 20, 2004 3:01 PM Subject: Re: [hlds_linux] OT funny (was: My server load of a FULL 64 PUB) > My point is. > > A server having 1000 FPS does not mean anything to the client.
