hm. I just checked again and found the runtime locally to be consistently only 11s, so not that long. Also in lord.arch, which is based on rotating disk and slower but still shows reproducibly 25s instead of the formerly very long runtimes. Maybe there was intermittent different behaviour based on some package updates.

I will give this some time and just recheck again at a later time how results within circleCI are. Maybe we can just reduce the timeout again.

From lord.arch:

Looking into the last 7 circleCI pipelines on master branch following https://app.circleci.com/pipelines/github/os-autoinst/openQA?branch=master I found times 65s, 52s, 51s, 51s, 53s, 54s, 60s so I think we can actually lower the timeout again: https://github.com/os-autoinst/openQA/pull/3454

To find out if there are any identifiable parts that contribute significantly to the long runtime I did:

$ unbuffer perl t/44-scripts.t | ts -i '%H:%M:%.S' | ts -s '%H:%M:%.S'

For explanation: unbuffer makes sure that every line is returned as soon as it is printed so that ts can display a sensible timestamp. The first timestamp is the runtime of the complete script whereas the second timestamp is the relative runtime difference to the previous line.

To me it seems that the perl scripts that use the mojo framework and especially our services using that each take about 1.2s of loading time which is quite significant but no single script stands out. With this I will unassign from the ticket again and expect that eventually someone will have a good idea how to optimize.
