Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org It seems that kernel nfsd consumes an inordinate amount of CPU time during writes on this machine. With a few hundred kb/sec being written over NFSv3 from a 2.2.17 client, all of the nfsd threads each consume as much of the available CPU time as possible. On a similarly configured machine with ext3 instead of reiserfs, nfsd consumes much less CPU time. Is there a known issue with NFSv3 performance and reiserfs? -- Brian Ristuccia - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
