My link is 10Mbit/s full duplex. I have set some HTB classes with a rate of 20% (2Mbit/s) and a ceil of 95% (9.5Mbit/s). Is such an excursion of bandwidth in the HTB classes feasible for HTB to control? What Timer frequency (kernel menuconfig) is the most suitable among 250, 300 and 1000Hz for HTB? Also, I really don't have any ideas on how the frequency could affect the network adapter performance. Is a high frequency going to have bad effects on interrupts handling? Has anybody any suggestions about this issue? I have some warnings about HTB quantums being too big, but as i understand, those should only affect the precision of the shaping without undermining the shaping completely. Thank you a lot. jack _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
