Comment 2 for bug 1957810

This is a build time comparison between linux 5.13.0-28.31 and 5.13.0-27.29

* amd64
  - before: 3 hours, 22 minutes
  - after: 2 hours, 19 minutes
* arm64
  - before: 15 hours, 49 minutes,
  - after: 15 hours, 12 minutes
* armhf
  - before: 10 hours, 59 minutes
  - after: 9 hours, 41 minutes
* ppc64el
  - before: 1 hour, 54 minutes
  - after: 1 hour, 32 minutes
* s390x
  - before: 44 minutes
  - after: 29 minutes

For the architecture that are suffering with longer build times and timeouts, arm64, there's only a marginal percentual improvement (less than 4%) in the build time meaning that there are other areas for improvements.

The build logs don't contain timestamps so we don't have the information about how much time it was taken to build the dbgsym packages, however with the apparent improvement of the build time for all architectures, even though this is a too small of a data sampling for an statistical analysis, we can consider this change to have been beneficial and successfully verified.
