Slow when typing name of the programs in WSL2 #899

Closed KingRayCao closed 1 year ago

KingRayCao commented 1 year ago

I'm using ubuntu 22.04.1 LTS via WSL2, and I find that there is a obvious lag when I try to type the name of the programs(e.g. ls, date, etc), but when I'm typing the arguments and flags ,everything goes fine. After I turned the plugin off, the problem was solved. Beside the plugin, I've also installed auto suggestion.

Encountered a similar issue. All typing was really laggy and was printing to the terminal in batches of 4 or so characters. I disabled the plugin and the lag was gone.

WSL2 Windows Terminal 1.15.2713.0 Debian 11 5.15.68.1-microsoft-standard-WSL2 zsh 5.8

Are you sure ALL the typing was slow? When I type in the arguments and flags, all things went fine. So I guess some problem encountered when the highlighting program checked whether some program is in the path. WSL2 Windows Terminal 1.15.2713.0 Ubuntu 22.04.1 LTS zsh 5.8.1

Yes it was (and does when re-enabled) no matter what I type

  1. Try zsh 5.9.
  2. I don't know that any maintainer has WSL, so, y'all may need to help investigate. Does it reproduce in zsh -f? Do make check and make perf work? Does zsh/zprof show anything (don't forget to zprof -c before starting the timed section)? Can you try a different terminal?

Looks like a duplicate of #790, so closing. Feel free to reopen if there's a distinction between the two issues.
