HI all, Watching vdsm travis builds in the last weeks, it is clear that vdsm tests on travis are about 4X times faster compared with jenkins builds. Here is a typical build: ovirt ci: http://jenkins.ovirt.org/job/vdsm_master_check-patch-fc24-x86_64/5101/consol... travis ci: https://travis-ci.org/nirs/vdsm/builds/179056079 The build took 4:34 on travis, and 19:34 on ovirt ci. This has a huge impact on vdsm maintainers. Having to wait 20 minutes for each patch means that we must ignore the ci and merge and hope that previous tests without rebasing on master were good enough. The builds are mostly the same, expect: - In travis we don't check if the build system was changed and packages should be built takes 9:18 minutes in ovirt ci. - In travis we don't clean or install anything before the test, we use a container with all the available packages, pulled from dockerhub. takes about 3:52 minutes in ovirt ci - In travis we don't enable coverage. Running the tests with coverage may slow down the tests takes 5:04 minutes in ovirt ci creating the coverage report takes only 15 seconds, not interesting - In travis we don't cleanup anything after the test this takes 34 seconds in ovirt ci The biggest problem is the build system check taking 9:18 minutes. fixing it will cut the build time in half. This is how time is spent in ovirt ci: 1.
