Neovim startup is slow in mac than in linux

Neovim
1

I use neovim 0.7, exactly the same config files in both OS. it’ll take 60ms to startup in linux but 180ms in macos m1 pro.
below is the part of --startuptime output , the difference lines:
this is mac:

103.941  087.375  087.375: sourcing ~/.config/nvim/init.lua
183.011  044.137: VimEnter autocommands

this is linux:

030.694  026.166  026.166: sourcing ~/.config/nvim/init.lua
059.600  010.673: VimEnter autocommands

I don’t know why, mac hardware is much better than linux, and no harddisk encrypt.
