Motivation:
After multiple improvements to other parts of our CI, the coverage job has become the longest-running task, limiting the total CI runtime.
This PR significantly reduces the coverage runtime from 16-18 minutes (already down from 26 minutes thanks to a previous improvement using an x64 16-core runner) to just 2 minutes—an 8-9x speedup.
Modifications:
Result:
The coverage runtime is reduced from 16-18 minutes (previously 26 minutes) to 2 minutes, achieving an 8-9x improvement.
