I tried your patch on a performance-critical system that I've been working on. Without going into a lot of detail, it's a bunch of in-kernel code that blasts packets back and forth between pairs of gigabit interfaces. Userland isn't involved at all. Running 4 gigabit ports in this way on a Dell 1950 with 4 CPU cores running at 3.0 GHz, I got about 4% better performance (in terms of packets per second) using your patch. That's a pretty good improvement, considering that the design makes some effort to avoid lock contention. JohnReceived on Tue Jan 16 2007 - 19:34:29 UTC
