Hello. I've been talking with John Ronciak about igb driver problems on Linux (RHEL 6 Linux bgp 2.6.32-71.el6.x86_64 #1 SMP Wed Sep 1 01:33:01 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux box) in shaper role, it seems problem is solved by disabling irqbalance daemon. For now we have builded new server with equal hardware: S5000PAL platform and E1G44ET (igb) network adapter. Basic role for this server is BGP router. But after testing we have got some strange behavior. It seems, that all working fine, iptables completely disabled, nf_conntrack modules not loaded, http pages are working fine, but when we try to load some other http pages, they are not working (could not load completely, but it's randomly - one time it loads and one time - no). We have read somewhere in Internet, that it's required to disable LRO, while routing, but it seems, that it's disabled by driver (ethtool -k), for example: Offload parameters for eth0: rx-checksumming: on tx-checksumming: on scatter-gather: on tcp-segmentation-offload: on udp-fragmentation-offload: off generic-segmentation-offload: on generic-receive-offload: on large-receive-offload: off So, is it truly disabled, or it should be done via insmod/modprobe arguments? And if it's disabled - what's wrong with our configuration? And maybe you can give us some assumption. (for example - some tcp tuning for igb driver) I should say, that this hardware is working fine for shaping, but for routing - no in our case.
