> - when I run just that test class locally from IntelliJ, it runs ~20
> seconds, with small Metaspace/heap consumption
> - on jenkins (there's maven module-level build parallelism with -T2),
> it runs 110-180s - no idea why it runs so much slower.
> - I tried several time running identical command as is running on
> jenkins [2], including version of JDK and memory settings == xmx=2G:
>     - the Heap/Metaspace usage didn't get near the 2G maximum (see
> screenshots from VisualVM from 2 runs)
>     - the running time of that SpeedTest was 40-80s
> - slaves used for full downstream build have 24G RAM + 8G swap, so
> lack of RAM shouldn't be an issue
> - there seems to be no connection to the issue you mentioned [3]
> - looking at history of this SpeedTest I see that you committed it
> initially as @Ignore, but Jozef later un-ignored it. Since this can be
> considered performance test and is failing randomly from time to time,
> I think we should mark it with @Ignore again. Wdyt? Any other ideas
> what I could check to troubleshoot this?
