@Olivier_Schmitt @Christophe_Havard @mickaelcaro - I think this would probably helpful in drill down above issue I was reading one of @Olivier_Schmitt comment so its worth sharing
We have 190 Projects right now in the solution and our build time increased as number of projects getting increased I’m suspecting(See below attached image)
was 250k +/- 6 months ago, now is 2250k +/- now
- the SonarCloud scanner scans every project = 190 analysis to perform
- each analysis takes 1 minute to scan the code which is quite fast (but can be improved if the scope is reduced to the minimum) = 190 minutes of code analysis. Even with a 30 seconds step, the build time will be multiplied by 8
To validate above theory I just change my build step to contain only one more project which has no reference to other project and it just took 32s 
Having said that what would you guys recommend and what should be minimum accepted time for scanning a project
Thanks in advance
