So `perf` is super slow on Ubuntu as well?
I feel for distro maintainers, real thankless job trying to square the circle on a billion different things like this.

Perhaps you should add a link to this article as a comment in that ubuntu bug tracker. That way it's useful for others who have the same question.

I'm sure it affects more people than that. Not everyone who experiences this bug is going to create an account on the ubuntu launchpad platform and write a comment about it
I'm absolutely positively sure that the amount of people using perf on Debian and derivatives (Ubuntu, Mint) is >>3
Definitely, I always assumed perf was just super slow, (having only really used it in anger on debian). Glad the next time I get sucked down a performance tuning rabbit hole, I can make the process a lot less painful!
I had done a bunch of research into this a while ago and filed an issue with the Ubuntu bug tracker, but was told it was due to ABI stability (which did not make any sense).

Understanding that there is actually an underlying license problem is like finally being told all of the reasons for everything that happened on LOST ;P.
