Too long to open a big file

[haifengkao]

It takes too long to open a big file.
nvim can open a big file in few secs.
But nyaovim takes a minute to open the same file.

Expected Behavior

should open the file within 5 secs

Actual Behavior

nyaovim takes a minute to open the file

Steps to Reproduce (including precondition)

1. download the 40MB json file https://raw.githubusercontent.com/Fngi/taipower_MAPS/gh-pages/result.json
2. open it with nyaovim

That's a Vim problem, nyaovim cannot help it.

As @justinmk said, Vim is not good at handling large files. Please try nvim in terminal to clarify the problem derives from backend (Vim) or frontend (NyaoVim).

You are right. Because I opened the file with nyaovim first, nvim can open the same file in few secs. If I open the file with nvim first, nvim is very slow as well.

@haifengkao Thank you for confirmation. 😃

@rhysd I am sorry. I was wrong again. nvim can open the same big file in few secs.
But it didn't display the file content until I press ctrl-c.

The ctrl-c stuff is related to the plugins.
If I open the file with nvim -u NORC result.json,
the file will be displayed instantly.

If the plugins are removed, nyaovim can open the same big file in few seconds.
If the plugins are added, nyaovim can also open the file in few seconds if users press ctrl-c.
In my experiments, nvim and nyaovim can open a 200MB file in seconds without any problem.
