Hi there,
We are experiencing extremely slow SonarCloud analysis performance, details below.

This seems to happen only on our trunk build, with our PR build we see SonarCloud take 3-4 minutes.
I set up a separate pipeline to run off a branch to troubleshoot this and I don’t get the same behavior. The branch is running a duplicated version of the main pipeline so the projects being built are exactly the same, just running against a branch instead of the main branch (which we call trunk)
Logs from branch build (note: there are no blank INFO logs on this build):

I believe the files listed under “Missing blame information for the following files” are just what has changed between previous head and the commit that this build is running against.
