This patch is very bad. It totally kills NFS performance in at least one of my usage cases. I mount a CVS repository by NFS and run cvs up against it. With this patch on the NFS server (BCM5761 A1), cvs up slows down by a factor of ten or so. I'm at a loss to explain how this happens; I don't see anything suspicious in netstat -I or -s. Ping doesn't show any unusual latency, bulk TCP traffic doesn't seem to be affected. The overall effect is perfectly reproducible, though. I get the same effect if this patch is present only on a client machine (BCM5702/5703 A2). -- Christian "naddy" Weisgerber [email protected]
