forcedeth throughput not correct

[John-Michael]

For the record, this system was upgraded from intrepid where this issue was not present.

Kernel: 2.6.28-11-generic

For some reason on the latest version of jaunty (up to date as of today) and for a while now my nvidia ethernet controller has not been performing as expected. I suspect this is a driver issue since the speed bottleneck is apparent in samba and the direct connect protocol. My speed in these programs seems to be capped at 5MB/sec regardless of if the link is 100Mb or gigabit. Previously I would get speeds of about 10MB/sec on a 100Mb connection and 20-30MB/sec on a gigabit connection. According to ethtool the link is negotiating properly (100Mb full duplex on a 100Mb connection.) This issue is independent of network-manager since I uninstalled NM and configured eth0 for dhcp in /etc/network/interfaces

00:05.0 Bridge: nVidia Corporation CK8S Ethernet Controller (rev a2)

If you need more info let me know.

Hi John-Michael,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/lucid.

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 362106

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
