Additional info:
Description of the patch with all benefits and caveats can be found on: http://kerneltrap.org/mailarchive/linux-netdev/2010/3/12/6271831 respectively in the commit message of Tom Herbert: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=0a9627f2649a02bea165cfd529d7bcb625c2fcad

Comment 3 Simon Reber 2010-11-18 15:21:26 UTC

Please include additionally RFS (Receive Flow Steering) patch as well - its a extension to the RPS patch and will help improve handling network traffic on a very busy server

Additional information are available on:

The commit message from Tom Herbert:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.36.y.git;a=commit;h=fec5e652e58fa6017b2c9e06466cb2a6538de5b4

I think there were already some fixes applied to the patch, but that's the basic commit, which made it into the kernel

Comment 4 Neil Horman 2010-11-22 15:32:44 UTC

This is a dup of bz 620680.  I've got a test build linked in there if you want to test it out.  If you can verify its working properly I'll post it internally for review.  Thanks!
