Nick Piggin d992895ba2 [PATCH] Lazy page table copies in fork() ... Defer copying of ptes until fault time when it is possible to reconstruct the pte from backing store. Idea from Andi Kleen and Nick Piggin. Thanks to input from Rik van Riel and Linus and to Hugh for correcting my blundering. Ray Fucillo <[email protected]> reports: "I applied this latest patch to a 2.6.12 kernel and found that it does resolve the problem. Prior to the patch on this machine, I was seeing about 23ms spent in fork for ever 100MB of shared memory segment. After applying the patch, fork is taking about 1ms regardless of the shared memory size."
