I wish you had started the thread by mentioning this specific
patch, we wasted an enormous amount of precious developer time
speculating and asking for arbitrary tests to be run in order
to narrow down the problem, yet you knew the specific change
that introduced the performance regression already...

This is a good example of how not to report a bug.
