Could this mean that we might want _both_ ? 1) a minimal guaranteed working set for small processes, so root can login and large hogs don't penalize good guys (simpler than the working set idea, should work just as good) 2) load control through process suspension when the load gets too high to handle, this is also good to let the hogs (which would thrash with the working set idea) make some progress in turns regards, Rik -- Virtual memory is like a game you can't win; However, without VM there's truly nothing to lose... http://www.surriel.com/ http://www.conectiva.com/ http://distro.conectiva.com.br/ -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
