So, my general view on this is that automated testing of performance
is nice, but unless it also comes with people willing to do the
work of identifying and fixing the causes of performance regressions
there's a risk that it degrades into another automated email or set
of graphs that nobody pays much attention to (outside of the obvious
"oops this commit dropped us by 50%" mistakes). As with fuzz testing,
I'm a bit wary of setting up an automated system that just pushes
work onto humans who already have full plates. Is RedHat also
planning to set performance requirements and assign engineers to
keep us from falling below them ?
