Synopsis: [msk] Slow network performance and high system cpu load while transfering data State-Changed-From-To: open->feedback State-Changed-By: yongari State-Changed-When: Mon Feb 22 02:01:24 UTC 2010 State-Changed-Why: I remember there are stability issues on 88E8072 but it's somewhat hard to fix that mainly because I don't have the hardware to narrow down the issue. It seems you have two issues here, low performance number and high CPU usage during transfers. I have no idea how high CPU usage comes from msk(4) even if msk(4) gives poor performance. Would you show me the output of "sysctl dev.msk.0.stats"? And send captured traffics on receiver side(not on host with msk(4)) with tcpdump and send it to me.
