Around a month ago, we switched filesystems from
overlay, based on this issue (https://github.com/concourse/concourse/issues/4570), because our worker CPUs were getting pegged and jobs were stalling/failing. Since then, we’ve noticed that a number of tasks will consistently take an additional 6-8 minutes to start, after the conclusion of the last task (when they had previously only taken ~15 seconds to start).
For example, there was an 11 second delay between the
ginkgo-cflinuxfs3 tasks here, and a 6 minute delay between the same tasks the next day (build 563 of that pipeline).
Is this avoidable? Can we shorten this time in between the tasks?
