Re: HTB ATM MPU OVERHEAD (without any patching)

I'm running some tests as you suggested. I'll have to wait til there are more players on my servers again before I can get some more accurate results, but preliminary tests show that 1) the overhead setting is quite significant and 2) my overhead value of 24 is a bit too low.

With overhead set at 24, the latency for the players is initially not greatly affected by adding an FTP transfer to the mix, but when I let the FTP run for a long time eventually the latency starts climbing. This would seem to indicate that something in the calculation is not quite right, and a buffer somewhere is slowly filling up.

This is just preliminary... hopefully I'll have something more solid tomorrow.

Those are always the thoughts I had. I never successfully played around with
overhead or MPU though. Did you compare results with and without using
overhead and mpu settings?
