Description

Motivation

With #158125 we have CPU load based limiting in place so we can try to increase again the number of worker instances on mania while ensuring that no typing issues crop up.

Acceptance criteria

  • AC1: mania is having significantly more worker instances enabled again
  • AC2: No typing issues show up on mania
  • AC3: Based on results from AC1+AC2 tickets exists with plans for all other o3+osd workers

Suggestions

  • Look into the reduction of worker instances done in https://gitlab.suse.de/openqa/salt-pillars-openqa/-/merge_requests/759/diffs, increase to a value even higher than the original 30 while carefully monitoring that the CPU load based limiting should prevent a system overload and related typing issues in openQA jobs
  • Based on results from AC1+AC2 create according tickets with plans for all other o3+osd workers
