------------------------------------
the problem with logs is that you need to get then "hot" be cause they may
disappear fast...
Older slave log (
fc24-vm15.phx.ovirt.org):
http://jenkins.ovirt.org/job/vdsm_master_check-patch-fc24-x86_64/5915/
{code}
...
12:01:51 Start: unpacking root cache
12:02:06 Finish: unpacking root cache
...
12:02:07 Init took 17 seconds
{code}
Newer slave log (
vm0125.workers-phx.ovirt.org):
http://jenkins.ovirt.org/job/vdsm_master_check-patch-fc24-x86_64/5916/
{code}
...
12:04:19 Start: unpacking root cache
12:05:15 Finish: unpacking root cache
...
12:05:16 Init took 57 seconds
{code}
Then again, on (newer)
vm0130.workers-phx.ovirt.org:
http://jenkins.ovirt.org/job/vdsm_master_check-patch-fc24-x86_64/5916/
{code}
...
12:02:45 Start: unpacking root cache
12:03:09 Finish: unpacking root cache
...
12:03:09 Init took 24 seconds
{code}
So not a 100% consistent result, still, we should find out how to get those 40 seconds
back...
BTW I was sure the local disk was mounted on older slaves with noatime, looks like that is
not the case, maybe we should fix that...
mock_runner.sh seems to run slower on newer slaves

Project: oVirt - virtualization made easy
Issue Type: Improvement
Components: Jenkins
Reporter: Barak Korren
Assignee: infra
After implementing speedup improvements for mock_runner.sh (Specifically enabling it to
deploy the chroot by extracting a tarball as opposed to installing it with yum every
time), I started monitoring run times for vdsm check_patch jobs.
I've noticed that jobs that are running on the old slaves (fc24-vm*) seem to
initialize mock faster then ones running on new slaves (vm*) - 17seconds vs 57 seconds
respectively.
I suspect this may be because the older slaves have a different FS mounted on
/var/cache/mock
