Maybe thats the source of the problem. Did you notice anything unusual in your logs concerning e1000 nics? >... >CPU utilisation is hovering around 50%, and load average is >consistently >under 0.1, so I don't beleive I'm looking at a CPU bottleneck. Is your box is multi-core (or HT-enabled)? Is your kernel SMP? If thats the case then check per core CPU utilisation (press "1" when watching top). You may be hitting roof only on one of the cores while avg. utilisation is around 50%. If you're not familiar with "smp_affinity", then you should read the following: http://bcr2.uwaterloo.ca/~brecht/servers/apic/SMP-affinity.txt cheers, Marek Kierdelewicz KoBa ISP _______________________________________________ Bridge mailing list Bridge@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/bridge
