This issue has been proposed when we are only considering blocker issues in the current Red Hat Enterprise Linux release. ** If you would still like this issue considered for the current release, ask your support representative to file as a blocker on your behalf. Otherwise ask that it be considered for the next Red Hat Enterprise Linux release. ** Does "ethtool -K ethX lro off" make something better ? Thank you for your bug report. This issue was evaluated for inclusion in the current release of Red Hat Enterprise Linux. Unfortunately, we are unable to address this request in the current release. Because we are in the final stage of Red Hat Enterprise Linux 6 development, only significant, release-blocking issues involving serious regressions and data corruption can be considered. If you believe this issue meets the release blocking criteria as defined and communicated to you by your Red Hat Support representative, please ask your representative to file this issue as a blocker for the current release. Otherwise, ask that it be evaluated for inclusion in the next minor release of Red Hat Enterprise Linux. I have these netperf results when using myri10ge on RHEL6. [root@dhcp-31-100 ~]# netperf -H 192.168.1.2 TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.1.2 (192.168.1.2) port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 87380 65536 65536 10.01 9874.51 Could you elaborate more about the problem (i.e. provide your configuration options)? Since RHEL 6.1 External Beta has begun, and this bug remains unresolved, it has been rejected as it is not proposed as exception or blocker. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. |
