Did you do any > benchmarking on that? I need to get a slower test-router so I can benchmark properly :( I need to get a very old pentium or high-end 486 with PCI. I implemented this a while ago and then accidentally lost the sourcetree but I did do some profiling which I can't find now :( A similar thing was recently done in VFS in kernel 2.5 for the atime updates and it gave a very nice speedup, I doubt the speedup will be as large here since the timer handling is a lot faster than disk-io. I'm currently in the process of going through the locking in conntrack to try and make it more scalable (splitting ip_conntrack_lock) and trying to fix things I find. -- /Martin Never argue with an idiot. They drag you down to their level, then beat you with experience.
