I'm just getting started on merging pre-fork from latest trunk into our own 0.28 setup. I know what you mean about the high load from forking 10 to 15Mb of exec image tens of times per second. For some reason kernel 2.6 appears to always drag the image out of swap, or so I infer from the amount being swapped in all the time with no corresponding swapout - even though it's forking a running process and hence ought be a RAM-to-RAM copy. I probably just don't understand enough about 2.6's VM allocation even though I've read all I can find on it :) But, at the glacial rate I'm allowed to work on our merge, I expect it to be some months before it's ready to handle live traffic and to try to reproduce your problem, sorry :-( Nick
