how to use the github benchmarks for branches

Hi,

Let us assume I just created some code that could improve performance 
and I want to compare this to existing benchmark results. Currently I 
would run the benchmarks for over 2 hours on my laptop, with unreliable 
results, locking me out of work - or maybe the jmh results that did run 
on my branch anyway. For the later I would like to know if I have to 
manually download all the artifacts for master and my branch, write a 
script that compares and then finally get an overview... Or we have 
something already that lets me see if my change improve or degrade 
performance?

bye Jochen
