Subject: Results of running lots_of_forks.sh for recent kernels.
Date: 13 Aug 2002 09:57:41 -0600 [thread overview]
Message-ID: <1029254261.2051.107.camel@spc9.esa.lanl.gov> (raw)
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.
