Queuing CPU Usage
Posted: Mon Mar 12, 2012 6:30 am
Hello All,
I have an x86 router (dual intel xeon 3.4) that is running about 150U / 350D of bandwidth through 2 providers. Each provider is a BGP peer and we are getting 2 full tables. Everything has been going very well for a very long time. We are starting to push more traffic and as a result the CPU is being used more. I was looking at the CPU usage with Profiler tonight and I noticed that there is anywhere from 10-15 percent CPU on queuing. We do not have a single queue on the system, only 1 input filter rule, no NAT, no connection tracking, no mangle, nothing of the sort really. I am wondering why CPU would be used on queuing then and if there are any other items that could affect this. I checked a similar setup core router (less the BGP) and the queuing on that box is less than 1 percent so I cannot understand why this box would have any more than that.
Any comments or tips would be appreciated!
Thanks all!
