Subject: 2.6.18-rc4-mm1 Run-time of Locking API testsuite
Date: Thu, 17 Aug 2006 14:06:56 -0600 [thread overview]
Message-ID: <44E4CC60.3080109@gmail.com> (raw)
Note the non-trivial execution time difference:
soekris:~/pinlab# egrep -e 'Locking|Good' dmesg-2.6.18-rc4-*
dmesg-2.6.18-rc4-mm1-sk:[ 16.044699] | Locking API testsuite:
dmesg-2.6.18-rc4-mm1-sk:[ 96.083576] Good, all 218 testcases passed! |
dmesg-2.6.18-rc4-sk:[ 18.563808] | Locking API testsuite:
dmesg-2.6.18-rc4-sk:[ 19.693692] Good, all 218 testcases passed! |
I diffed the respective configs, saw nothing obvious in the following,
some of them look like theyd favor -mm1, if anything.
<trimming the obvious irrelevants>
[jimc@harpo lxbuild]$ diff linux-2.6.18-rc4-sk/.config
linux-2.6.18-rc4-mm1-sk/.config
