I had tried few simple cases, and it was moreover correct. On 100s for small subset it run aporx double the time. On 30m on same subset it run moreover correctly, however "real" deplyment went awefully wrong:


I split all the jcstress to 20 huge groups, and gave each 30 minutes. So quite good coverage which will on 2-6 machines finish pretty quickly.
However morning, 12hours later, only two sets were finished:

Limit is 500; no group with more then 500 of tests should be merged to bigger ones. Exclude list is of length of 4
Small groups will be created.
Huge groups will be split to more subsets. Exclude list is of length of 0
Only N from FQN will be used. This saves space, but risks duplicate matches
Cores limit for final playlist is not used
