You have the perfect configuration now. As Gary said, leaving applications in memory is exactly what you need for your latency-sensitve game server. If you're already not using any appreciable amount of swap, then lowering the value would not make a difference for you, because the system would simply continue to not use swap. Raising the value significantly would cause Linux to swap to disk more aggressively, which would lead to lesser-used L4D (and other application) memory being paged to disk and to a larger in-memory system-level disk cache. Level loads then might happen faster, but if someone were to join the server and cause L4D to touch some memory currently stored on disk (say, by moving to a part of the map that hadn't been seen in awhile), there would be a noticable delay while the system retrieved the on-disk page (Microsoft would call this a "hard fault"). In other words, the game would stutter. -John _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds_linux
