Hi
We recently published a guide to investigate performance issue, you can find it here: The Sonar guide for investigating the performance of .NET analysis .
Some ideas:
- looking at the detailed logs to work out where the test coverage that is imported is being generated so they can work out which steps they really need to run
- exclude the shared projects from this analysis and analyze them separately in a separate pipeline with a separate SC project - it is not optimal, however, like this they will only be analyzed once
Please check out the guide and come back with any additional questions.
