Message-ID: <20080214162104.GA5347@ics.muni.cz> Date: Thu, 14 Feb 2008 17:21:04 +0100 From: Lukas Hejtmanek <xhejtman@....muni.cz> To: linux-kernel@...r.kernel.org Subject: Disk schedulers Hello, whom should I blame about disk schedulers? I have the following setup: 1Gb network 2GB RAM disk write speed about 20MB/s If I'm scping file (about 500MB) from the network (which is faster than the local disk), any process is totally unable to read anything from the local disk till the scp finishes. It is not caused by low free memory, while scping I have 500MB of free memory (not cached or buffered). I tried cfq and anticipatory scheduler, none is different. -- Lukáš Hejtmánek -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
