ZSH lag

I recently moved to zsh from bash, but am having an issue with the autocomplete plugin.

When I run pacman -S packagename it lags heavily. Possibly too many suggestions? Other commands seem ok so far.
I use alacritty but also tested with konsole with the same issue.

my .zshrc looks like this:

source /usr/share/zsh/plugins/zsh-autocomplete/zsh-autocomplete.plugin.zsh

HISTFILE=~/.histfile
HISTSIZE=500
SAVEHIST=500
setopt autocd beep extendedglob nomatch
bindkey -v

zstyle :compinstall filename '/home/user/.zshrc'

alias ff='fastfetch'
alias vim='nvim'
alias ls='ls --color=auto'
alias grep='grep --color=auto'

Disabling the plugin solves the issue, so it must be the plugin. I installed the plugin via pacman of course.

Any help would be appreciated! Thanks

Re: ZSH lag

Ftr, that's autocomplete-as-you-type, not regular tab-driven autocomplete.
"pacman -S" autocompletion is (initially) slow, yes. (pacman -Sql will produce 15.000 results, if it's run on every keypress, that's gonna be a problem of sorts)

Does https://archlinux.org/packages/extra/an … ggestions/ behave better?

Thanks for your reply.

zsh-autosuggestions does behave much better. No lag with that one.

I did think it might simply be the amount of possible suggestions. I found a similar report on their https://github.com/marlonrichert/zsh-au … issues/736

Maybe it is the plugin simply being a victim of its own success by suggesting too much.

If it wasn't clear, the lag occurs as you type the package name. So if I did sudo pacman -S zsh-,,, as each key is pressed it is lags and stutters, I assume as it tried to query every possible match.
