From mboxrd@z Thu Jan 1 00:00:00 1970 Date: Mon, 2 Oct 2000 11:20:30 -0700 (PDT) From: Linus Torvalds Subject: Re: TODO list for new VM (oct 2000) In-Reply-To: Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-linux-mm@kvack.org Return-Path: To: Rik van Riel Cc: linux-kernel@vger.redhat.com, linux-mm@kvack.org, Matthew Dillon List-ID: Why do you apparently ignore the fact that page-out write-back performance is horribly crappy because it always starts out doing synchronous writes? I pointed out previously in a private email that page_launder() must be buggy as it stands now, you seem to have ignored that part (and the test-program that shows 1MB/s writeout speeds due to it) completely. The whole _point_ of the new VM was performance. Without that, the new VM is pointless, and discussing TODO features is equally pointless.
