From: Steven Cole To: Andrew Morton Cc: Linux Kernel , Alan Cox Content-Type: text/plain Content-Transfer-Encoding: 7bit X-Mailer: Evolution/1.0.2-5mdk Date: 23 Oct 2002 13:42:13 -0600 Message-Id: <1035402133.13140.251.camel@spc9.esa.lanl.gov> Mime-Version: 1.0 Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 2216 Lines: 86 Greetings all, I performed some timing tests for 2.5.44 mm3 and ac2, using tar zxf of the 2.5.44 tarball and rm -rf of the resulting tree as the load. I performed each of these 4 times. There was some variation between runs, but not as much as between kernel versions. This data comes from the first of the 4 runs in each case. The hardware was a single PIII, kernels were UP, PREEMPT. All partitions are on the same disk, a ST340016A ATA. For mm3, SHAREPTE was not enabled. This is not intended as a comparison between filesystems, since each is on a different part of the disk. But the reputation for reiserfs to be able to delete files quickly seems deserved. The side-by-side numbers are intended to show the amount of regression for each fs. Yes, I know it would be nice to compare plain 2.5.44 too, but there is only so much time in the day.
