Hello, guys! I have router that shape traffic with cbq+sfq and everything was working fine until today when I put two more files one for upload and one for download, and I get high latency about 20-30ms the usage of CPU0 is about 100%. if I remove these two files then everything is back to normal. With these two files I have more than 2222 files one for upload and one for download. There is no difference between these two files and other files I think that the problem is with number of rules. Is there any limits for sfq and can I increase them? router hardware configuration: dual p4 xeon 2.4Ghz ; 1GB/ram ; two nics e1000/64bit running kernel is 2.4.27 traffic that pass through router is about 300mbps 40-50kpkt/sec Any help, suggestions or comments on that will be appreciated.
