I meant 'test root dir'/test sub groups (as they usually maps). I can't force the issue.. it seems to work fine... But plenty of times the machine have been running just one test and that timeouts it starts a whole bunch of new tests from another test group. Is this recently fixed, or what may be the issue? E.g. +robbin = \ + compiler/c2/irTests \ + runtime/handshake It runs tests from both groups in parallel, which is not what I have been seeing? > Given the execution times, I wonder if you've looked at using the finer grain > test groups and splitting the execution across a number of machines.

Running on my workstation with qemu-user or a small rv64 board there is around 50x time vs x86 for me. It helps, but requires a bunch of machines. ------------- PR Comment: https://git.openjdk.org/jdk/pull/24229#issuecomment-2754202998
