Breakdown of time spent on job, net time as summary

[Simon Richter]

Hi,

I have several matrix jobs running either because of a timer or a
commit, and some of these take ages. In total, I still get by with a
single executor, however individual matrix configurations get stuck in
the queue for extended times, which still counts as execution time for
the top level jobs.

Similarly, a lot of time is spent each time on transferring artifacts
between builds, and this is also fairly unpredictable.

Is there a way to get finer-grained details about the time spent, so
that I can easily ignore SCM actions and artifact transfer for the build
time display, and can I somehow use the "net" build time (running the
"main" build step) as the build time for a job in order to have
comparable values over time?
