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 3

Hi Fabizio, Ignore my last mail direct to you, 638976 PPS is awful. (today is a national holiday here, my brain is not switched on). To me it looks like interrupt coalescing is not switched on for some reason. Are you passing any parameters to the driver in boot.conf. Could you retest with vmstat

Re: Test on 10GBE Intel based network card

If you go to FreeBSD 8 you will get the improved stack code, and the RX/TX queue pairs will be pinned to cpus. It should improve performance. Make sure you have enough mbuf memory allocated, try increasing the descriptors. Jack On Mon, Aug 3, 2009 at 3:26 AM, Invernizzi Fabrizio < fabrizio.inve

Re: Test on 10GBE Intel based network card

what about your sysctls? I would like to see what have you done yet. Here is a previous conversation about that: http://www.mail-archive.com/freebsd-performance@freebsd.org/msg02293.html Actually I am not aware of the chan

Re: Test on 10GBE Intel based network card

Nice, I guess to analyse the bottlenecks you might want to use dtraceIf it is working with 7.2, I am not sure about that. Regards, Istvan On Mon, Aug 3, 2009 at 11:17 AM, Invernizzi Fabrizio < fabrizio.inverni...@telecomitalia.it> wrote: > HI > > These are the sysctl vars you pointed out > >

Re: Test on 10GBE Intel based network card

Hi, The limitation that you see is about the max number of packets that FreeBSD can handle - it looks like your best performance is reached at 64 byte packets? Am I correct that the maximum you can reach is around 639,000 packets per second? Also you are not routing the traffic, but instead

Test on 10GBE Intel based network card

Hi all I am doing some tests on a BSD system with a 10gbe Intel based network card and I have some doubts about the configuration since the performance I am experiencing looks (very) poor. This is the system I am doing test on: - HP 380 G5 (XEON X5420, CPU speed: 2.50GHz, BUS speed: 1333 MHz
