Just for the record:
I can also reproduce on my x86-linux laptop. I started at 1000, and each
thousand I added almost multiplied the time by 2.
I then tried with a debugger based on 6.8, just to see what type of behavior we
get, and it seems linear: Each thousand I added added an extra ~120ms (I tried
from 1000 to 10_000).
