Hi,
Out of curiosity, I timed 'emacs -Q' scrolling through an elisp buffer: I
started the timer
by hand and scrolled down for 1000 lines and it took 45s on Windows/WSL
and 35s on Windows/native.
This is on a pretty decent laptop (core i7, 32Gb ram, 4k display)
I don't care about the difference here, but overall,
I find it pretty slow. Is there something that could be done to enhance it?
What is the main bottleneck here?
Best regards,
Fabrice
