I hope this is the right place to ask this. Does any know if there is a substantial difference in the performance of the traffic controller between kernel 2.4 and 2.6. We tested it using 1 iperf server and use 250 and 500 clients, altering the burst. This is the set-up: iperf client - router (w/ traffic controller) - iperf server We use the top command inside the router to check the idle time of our router to see this. The results we got from the 2.4 kernel shows around 65-70% idle time while the 2.6 shows 60-65% idle time. We tried to use MRTG and we're not getting any results either. We want to know if we could improve the bandwidth by upgrading the kernel, else we would have to get a new bandwidth manager. Have anyone performed a similar test or can suggest a better way to do this. Thanks in advance.
