Without the 100ms, I think TeXmacs is still slow. We have to carefully review our code.

+ We should remove unnecessary computations. For example, this bug: https://savannah.gnu.org/bugs/?56364 .
+ For necessary time-consuming operations, a progress bar should be presented or make it lazy/async.

Personally, I revert this commit when building TeXmacs. It is a 100ms delay.

Just press "a" for 10 seconds, you will the difference with or without the commit.

Hi all,
I found this comment in hackernews:

"
The keyboard latency makes this program completely unusable! I've been following the project for the last two decades hoping someday it would be useful to touch typists who type around 120 wpm. Until then ... I just keep using emacs + auctex. Sure looks nice though.
“

“
NB: I tried both slowphil's custom build on github and the native windows binary downloadable from the main web site. Typing lag (estimated at 500-800ms) is totally unacceptable in both instances.
“

do you people feel that this comment is correct? and that we have a latency problem?

With the last TeXmacs I also experience some slugginess while writing slides.

Do we have a problem here? Or is just an impression?


Best
Max
