Unfortunately no. The reasons are that that data was misleading because

Every run takes 1-2 h so doing 1000 would be certainly time-consuming :)

Hi Pablo,
thanks for pointing this out.
Would it be possible to get the data for older runs back, so that
it's easier to find the changes which caused the slowdown ?
Going to the timeline, it seems that the system only has data
for Oct 14 (today):

Unfortunately no. The reasons are that that data was misleading because
different points were computed with a different version of pyperformance
and therefore with

Those are also micro-benchmarks, which can have no effect at all on
macro-benchmarks. The ones I am
linking are almost all macro-benchmarks, so, unfortunately, the ones
in Python 3.9 "What's New" are
not lying and they seem to be correlated
The performance figures in the Python 3.9 "What's New" (here -
https://docs.python.org/3/whatsnew/3.9.html#optimizations) did look
oddly like a lot of things went slower, to me. I assumed I'd misread
the figures, and moved on, but maybe I was wrong to do so...
