8267229: Split runtime/Metaspace/elastic test configurations for better scalability #4047

wants to merge 2 commits into from


Copy link

@shipilev shipilev commented May 17, 2021

JDK-8251158 added runtime/Metaspace/elastic tests that run in hotspot:tier1. Unfortunately, those tests are quite long, and they contribute to long tail in hotspot:tier1 on larger machines. We can split the test by configuration for better scalability.

Attention @tstuefe.

Additional testing:

  • affected tests on Linux x86_64, fastdebug/release
  • hotspot:tier1 on Linux x86_64, fastdebug

Very good, thanks for doing this.

BTW I plan to move part of them out of tier1 after JDK17, but atm would like to leave them in tier1 since Metaspace gets still worked on and JEP 387 is still fresh.

Cheers, Thomas
