SonarCloud .NET build going from 2-3 minutes for a build to just under 23 minutes

[mitchelsellers]

I have been trying to find ways to improve performance, we went from 2-3 minutes for a build to just under 23 minutes with SonarCloud. Using the above recommended setting I’m down to 18 minutes, but still trying to get way better than that if I can.

Hello @mitchelsellers

Thanks a lot for the feedback.

You can read some advice in the The SonarSource guide for investigating the performance of .NET analysis

I’d suggest to make sure:

@Andrei_Epure

Make sure you do not run the analysis twice

And to increase the number of CPUs:

@Andrei_Epure

Increase build machine resources

Static code analysis is resource intensive. By increasing the number of CPUs on your build machines, MSBuild will run concurrently. When analysing various open source projects with Sonar, we have seen significant improvements when increasing the CPU count.

For example, the tables below show that increasing from 4 CPUs to 8 CPUs can reduce the analysis time by almost 40%.

Also, if you want to help us identify anomalies in rule performance, please share with us the diagnostic reports as specified in the guide:

Thanks a lot in helping us make the products better!

@Andrei_Epure thank you for the response, a few notes from my side.

• We are using GitHub actions, so without creating a custom runner, we don’t have any ability to increase the resources. And honestly this is a smaller project (similar results with other projects)
• We are for sure only running the build once
• What is the best way to send you a log?

Hi @mitchelsellers , sent you a private message (accessible via https://community.sonarsource.com/t/re-sonarcloud-net-build-going-from-2-3-minutes-for-a-build-to-just-under-23-minutes/69207).

Fair point… Let’s have a look at the logs, maybe I can give advice based on that.
