Subject: VM test on 2.4.14pre3aa2 (compared to 2.4.14pre3aa1)
Date: Sun, 28 Oct 2001 12:07:21 -0500 [thread overview]
Message-ID: <20011028120721.A286@earthlink.net> (raw)
Summary: 2.4.14pre3aa2 gave oom errors not seen in 2.4.14pre3aa1.
Test: Usual scripts to execute mtest01 and mmap001.
Listen to long mp3 with mp3blaster.
mtest01 -p 80 -w
================
2.4.14pre3aa1
Averages for 10 mtest01 runs
bytes allocated: 1246232576
User time (seconds): 2.105
System time (seconds): 2.773
Elapsed (wall clock) time: 59.503
Percent of CPU this job got: 7.80
Major (requiring I/O) page faults: 132.8
Minor (reclaiming a frame) faults: 305043.1
2.4.14pre3aa2
Averages for 10 mtest01 runs
bytes allocated: 1254201753
User time (seconds): 2.211
System time (seconds): 2.794
Elapsed (wall clock) time: 65.176
Percent of CPU this job got: 7.20
Major (requiring I/O) page faults: 129.7
Minor (reclaiming a frame) faults: 306988.9
mmap001 -m 500000
=================
This test worked on 2.4.14pre3aa1, but on 2.4.14pre3aa2, each
iteration was terminated by signal 9. Also an irc client I
had running was killed.
