Re: Test on 10GBE Intel based network card

Hi all, cpuset is the command to set a cpu affinity, there are details @ http://bramp.net/blog/post vmstat -z is the command you need to determine whether there is contention for mbufs. although the cpu usage does not suggest the system is memory constrained. Regards Ray Kinsella On Mon, Aug

Re: Test on 10GBE Intel based network card

vmstat switched on "vmstat 3" and send us the output. I expect we are going to see alot of interrupts. Regards Ray Kinsella On Mon, Aug 3, 2009 at 4:19 PM, Ray Kinsella wrote: > Hi Fabrizio, > > I am an Intel Network Software Engineer, I test/improve the performance of >

Joseph, I would recommend that you start with PMCStat and figure where the bottleneck is, Given that you have a two threads and your CPU is at 100%, my a apriori guess would be a contention for a spinlock, so I might also try to use LOCK_PROFILING to handle on this. Regards Ray Kinsella On
