Egentlig er jeg også overrasket over hastigheden, for jeg har på ingen måde forsøgt at optimere Apache. Et opstået problem er derimod at Apache har fået Linux til at overcomitte, noget jeg nok kigger på ved lejlighed så OOM ikke kommer frem fra dybet. Ved samme lejlighed skifter jeg nok over til MPM Event, for den skulle kunne parkere alle keep alive forbindelser i en billig tråd så de noget dyrere server tråde kan bruges til at levere indhold

Under en af søgningerne fandt jeg en noget humoristisk måde at kritisere overcommit og OOM
http://lwn.net/Articles/104185/An aircraft company discovered that it was cheaper to fly its planes
with less fuel on board. The planes would be lighter and use less fuel
and money was saved. On rare occasions however the amount of fuel was
insufficient, and the plane would crash. This problem was solved by
the engineers of the company by the development of a special OOF
(out-of-fuel) mechanism. In emergency cases a passenger was selected
and thrown out of the plane. (When necessary, the procedure was
repeated.) A large body of theory was developed and many publications
were devoted to the problem of properly selecting the victim to be
ejected. Should the victim be chosen at random? Or should one choose
the heaviest person? Or the oldest? Should passengers pay in order not
to be ejected, so that the victim would be the poorest on board? And
if for example the heaviest person was chosen, should there be a
special exception in case that was the pilot? Should first class
passengers be exempted? Now that the OOF mechanism existed, it would
be activated every now and then, and eject passengers even when there
was no fuel shortage. The engineers are still studying precisely how
this malfunction is caused.
