How about reporting your
grep -m1 '^model name' /proc/cpuinfo
along with the stock Ubuntu package version's time on a reference
position when given 1, 2, ... threads. And then you're self-compiled
version for comparison, noting what you changed in debian/rules.
It would be a start, and also offer some precision so if something is
awry then others on the list may have data to judge by.
