Date: Tue, 11 Jul 2006 23:03:12 +0200 Message-ID: Mime-Version: 1.0 Content-Transfer-Encoding: quoted-printable Return-path: list-help: list-unsubscribe: list-post: Errors-To: flx@namesys.com List-Id: Content-Type: text/plain; format="flowed"; delsp="yes"; charset="iso-8859-1" To: "reiserfs-list@namesys.com" Hi I got problem with apps that are calling fsync, it makes my hard drive =20 flush like mad and it slows down things quite a lot. Example: I'm using amarok and amrok uses sqlite for storing data, sqlite calls =20 fsync after every write so on song change amarok writes to sqlite some =20 statistic data about what I listen and sqllite calls fsync, now I got =20 amarok trying to load next song and sqlite fsyncing and the problem is =20 that fsyncing under reiser4 is expensive, it takes a lot of time even if =20 I'm only running amarok and nothing else ( I got 4200RPM drive in my =20 notebook so it;s not a speed daemon). I patched sqlite in amarok to fake = all fsync and it fixed it but there are other apps that try to secure my =20 data by syncing (I'm now running azareus and only fsyncs called every =20 minute can explain writing to disk at full speed almost non stop while I'm = =20 downloading only 64KB/s ). So my question is: is there any way to disable fsync for reiser4? (beside = patching it to fake fsync instead of doing them). Thanks for great fs. =A3ukasz Mierzwa
