Hi @mickaelcaro,
I think we are having the same problem. We have a solution with 50+ projects with 2M+ loc and build duration increased from 15-20 minutes to 80-100 minutes after adding SonarCloud step to our Build Pipeline on Azure DevOps.
I would like to learn what happened with @tank104 's case. May be we can benefit from them.
Thanks in advance,
Best regards,
