Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-linux-mm@kvack.org Return-Path: To: linux-mm@kvack.org Cc: Linus Torvalds List-ID: Hi Linus, I'm reading the pre8 code now and I see that the anti-hog code is gone. I'm still busy developing the active/inactive list thing, but was just doing a short test with pre8 and noticed a *sharp* increase in the amount of filesystem IO when a big memory hog is swapping ... In addition, I'm seeing smaller processes blocked on disk; this didn't happen as often when the anti-hog code was still in and drastically reduces throughput for the memory hog (who now has to wait in line for disk accesses). I'm curious ... why was the anti-hog code taken out? It helps quite a bit on systems which are more or less low on memory (ie. not your normal working environment, but common in universities and lots of countries all around the world). regards, Rik -- The Internet is not a network of computers.
