[bug]: source .zshrc runs slower after repeating

[QuasarRyan]

What happened?

Running source .zshrc or source ~/.zshrc takes longer and longer after repeating it. Use exec zsh or just zsh to restart the env will fix but repeating source .zshrc or source ~/.zshrc will still takes longer and longer. Use time (source .zshrc) or time (source ~/.zshrc)

Steps to reproduce

Add the following lines to .zshrc file and run source .zshrc again and again for a few times.

ZINIT_HOME="${XDG_DATA_HOME:-${HOME}/.local/share}/zinit/zinit.git"

# Download zinit, if it's not there yet
[ ! -d $ZINIT_HOME ] && mkdir -p "$(dirname $ZINIT_HOME)"
[ ! -d $ZINIT_HOME/.git ] && git clone https://github.com/zdharma-continuum/zinit.git "$ZINIT_HOME"
#
# Switch the download link to my self-host repository Mirror
# [ ! -d $ZINIT_HOME/.git ] && git clone https://git.xcreeper.xyz:4433/Qu
# asarRyan/zinit.git "$ZINIT_HOME"
# Source/Load zinit
source "${ZINIT_HOME}/zinit.zsh"

Relevant output

Screenshots and recordings

It's running slower and slower.

It not just happens on macOS. This is Proxmox LXC Debian 12.7 bookworm.

Use exec zsh or just zsh once or just time (source .zshrc) for one or two times will fix.

Operating System & Version

OS: darwin24.0 | Vendor: apple | Machine: x86_64 | CPU: arm64 | Processor: arm | Hardware: arm64

Zsh version

zsh 5.9 (arm64-apple-darwin24.0)

Terminal emulator

xterm-ghostty and xterm-256color

If using WSL on Windows, which version of WSL

None

Additional context

I didn't show the whole .zshrc file because even if there's # conda initialize and lots of export, removing the zinit itself will get rid of this and that's why I create this issue here in this repository. It happens on Apple Terminal too, and using ssh to connect to Proxmox LXC Debian 12 with the same .zshrc configuration won't help.

Code of Conduct

[QuasarRyan]

The environment on Linux is as written below:

• Debian 12 bookworm
• zsh, fzf, lsd, git installed with package manager
• ohmyposh, zoxide with manual install in $HOME/.local
• enable en_US UTF.8 UTF.8 and zh_CN UTF.8 UTF.8 in /etc/locale.gen with this in .zshrc file but you can just remove these plugins, auto complete, fzf, zoxide and ohmyposh configuration.
