[opensuse] bonding again - performance issues
Hello, I set up bonding on our SUSE machines as described in a thread from a few weeks ago. Instead of boosting network performance, the effect was to degrade network performance significantly.. The setting was the "rr" round robin setting. Can someone suggest an alternate approach? The servers in question are a CVS server and an apache web server. The performance when pulling the cvs tree was far lower with bonding enabled than when using a single network card. In addition, some network applications would not work at all with bonding enabled (specifically Orcad License Server That may be related to the fact that the License server is licensed to the MAC address of one of the network cards.) This is on 64 bit OpenSUSE 10.2 and 64 bit SLES 10.2. Thanks, Joel -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Thanks,
Joel Any services that are aware of the MAC address will need to be reconfigured to the mac address generated by the bond pair. this may also be a part of your other problem of speed. If the network has a lot of clients looking for that original MAC address and they can for some reason see it but it doesn't respond (because the bond pair is responding not the individual cards) then the retries to the original MAC would cause the server to respond slowly to other requests. -- James Tremblay Director of Technology Newmarket School District 213 S.

Hi Patrick, It was purely subjective testing - engineers pulling CVS trees complained of snail slow performance. We turned off bonding, and now we have very fast performance. Not a scientific test, so I don't know if posting a bug report is a helpful thing. - Joel Patrick Kirsch wrote:
