We have an internal thing for drawing trends & showing data from test runs
automated with Jenkins, which still happens to be running some 3D tests.
When I had still time for Mesa, I used this tool to bisect performance changes
I saw in the trends:
<a href="https://cgit.freedesktop.org/ezbench/tree/README">https://cgit.freedesktop.org/ezbench/tree/README</a>
<a href="https://www.x.org/wiki/Events/XDC2016/Program/peres_ezbench.pdf">https://www.x.org/wiki/Events/XDC2016/Program/peres_ezbench.pdf</a>
(It automatically bisects all performance and rendering changes in given tests,
between given commit range in given repo, which is very handy. I don't know
any other tool that does both, although whether rendering has changed is
important info for evaluating performance changes.)
Few people in Mesa team have used this:
<a href="https://gitlab.freedesktop.org/mesa/sixonix/commits/master">https://gitlab.freedesktop.org/mesa/sixonix/commits/master</a>
(It does much less than ezBench, but is simpler to use.)</pre>
