From: Steven Cole Content-Type: text/plain Content-Transfer-Encoding: 7bit Date: 13 Aug 2002 09:57:41 -0600 Message-Id: <1029254261.2051.107.camel@spc9.esa.lanl.gov> Mime-Version: 1.0 Sender: owner-linux-mm@kvack.org Return-Path: To: linux-mm@kvack.org Cc: Steven Cole List-ID: I ran Daniel's lots_of_forks.sh test for several kernels. http://people.nl.linux.org/~phillips/patches/lots_of_forks.sh I realize that this may be like dbench in that it is not a realistic real world test, but the numbers may still be interesting. Note the much larger variance in the 2.5.x system times. 19p713b = 2.4.19-pre7-rmap13b speedup = same as above with speedup patch -pre2 = 2.4.20-pre2 Numbers are System time as reported by time -v. The machine is 2-way p3, SMP kernels, configured the same, no tweaks to /proc/sys/vm. The test was performed 8 times with no delay between runs. 19p713b speedup 2.4.19 -pre2 2.5.28 2.5.31 1 34.46 31.47 24.71 24.96 39.91 37.04 2 33.93 31.78 24.64 24.92 44.91 45.88 3 33.87 35.76 24.95 24.69 48.63 44.89 4 34.48 31.11 24.97 24.39 58.12 55.8 5 34.46 31.78 24.67 24.72 49.81 43.18 6 34.49 31.1 25.1 24.34 57.62 40.93 7 34.03 31.47 24.43 24.64 50.42 47.27 8 33.84 31.71 25.04 24.53 45 36.49 I have the output of time -v sh lots_of_forks.sh for these tests if anyone is interested.
