You all do realize that this is not as simple as installing your
favorite benchmarking application and execute it on a all debugged
turned off rawhide right. The benchmarking needs to be run for a certain
amount of time to notice potential trends. The output needs to be
analyzed from the benchmarking test(s) and the tests need to be repeat
with several different compile options and performed on several
different architecture again repeated if application(s) that are being
benchmarked have various tuning knobs. Then when it has been correctly
identify which application(s) are performing *badly* the code needs to
be profiled, improving areas in the code correctly identified,
suggestion or a patch proposed to upstream etc etc etc ...
If there is enough will and manpower to deploy a proper *performance
testing* environment and infra has enough resource to host it. Get
together create a Performance SIG and ask infra for resource. If not I
suggest you continue to watch the outcome from those phoronix tests,
stare at system monitor or create your own graphs in calc.
