Hello... Just a question from a user... :) I was just wondering if Rik van Riel's VM patches might possibly be integrated into 2.4.0-testX anytime soon? I have been having very good experiences with Riel's latest patches in both a desktop and light server environment. On the desktop, Riel's vmpatch against 2.4.0-test8 is significantly better then 2.4.0-test8's performance. Operation seems much faster and smoother. In fact, I'd say it could even be much better then whats floating around in 2.2.x now! Just a couple of examples on where the differences in Riel's patches become apparent (though one might argue that they are useless indicators).... I have recently been having difficulty with Loki Games's latest patches for the game Unreal Tournament. The problem is it leaks memory very quickly. After about two minutes of gameplay the process takes up 300+MB of memory with an increase of around 10mb per minute. This machine only has 256mb of ram so you can imagine that it starts to swap at that point. Usually under 2.2.x it takes about 4 minutes of gameplay before I hear my harddrive screetch and the game starts becoming unresponsive. With Riel's patch and 2.4.0-test8, I can sometimes play for up to 6 minutes before the swapping makes the game unusual. Is Riel's patch more efficient at swapping or something? Another example... Start Quake3, join a game on the internet and play for about 5 minutes. Then quit and go right back into the game. With Riel's patch the harddrive is only touched for a brief second. With 2.2.x the harddrive is touched for a few seconds while quake3 loads the maps, etc that were played before. Riel's patch seems to keep things cached in memory much more efficiently. And yet another example... mkisofs on my system is a dog with 2.4.0-test8. It kills performance of other applications and makes mp3 players skip etc. There is no skipping and "freezeups" with Riel's patch. Although mkisofs seems slower under 2.4.0-test8+vmpatch then stock 2.2.x, Riel's VM seems to be much "smoother". I tried Riel's patch on a lightly loaded webserver. Though because of the lack of any substantial load on the system I don't think its worth commenting on it... Perhaps other people could comment on their experiences? I am looking forward to vmpatch with the planned IO tweaks and out of memory handler... I would hate to have to patch the VM system throughout the 2.4.x stable tree with his patch so I'm lobbying for it to be included. :) Just my opinions and experiences... please feel free to flame away if I am misunderstanding something... Thanks for your time. -------------------------------------------------------------- Bruce A.
