In that case, I suggest reverting the change. The problem I was describing has far starker consequences -- 100-to-1 or more in terms of performance. If you're only seeing a few percent difference, then the problem I described (and that affects me) almost certainly cannot be your problem. > r...@seraph:~# kstat -m e1000g -i 0 > ... > XOFFs_Recvd 106 > XOFFs_Xmitd 0 > XONs_Recvd 2 > XONs_Xmitd 0 > Xmit_TCP_Seg_Contexts 0 > Xmit_TCP_Seg_Contexts_Fail 0 > Xmit_with_No_CRS 0 It's still interesting that you're getting XOFF (flow control) messages from your local switch. It suggests that your switch is bandwidth-limited in some way. Are both peers in this test at 1Gbps? Is it possible to try a different switch? -- James Carlson 42.703N 71.076W <[email protected]> _______________________________________________ networking-discuss mailing list [email protected]
