Im reading ant playing with polling and kernel..... I read that polling increase net performance and i plan on using it... Now the question that arises is.. is polling and performance in general affected by the value of kern.hz? i have put in /boot.loader.con kern.hz=50 and was wondering if this number affects the number i choose for the polling options I wanna recompile kernel using options DEVICE_POLLING options HZ=1000 So that 1000hz how affects the system? if it affects it at all........ thanks for anyone who can give me a hint.... Cheers, A
