100% cpu usage on Os X M1 pro (with ARM)

[marosiak]

Hi, I am using lazyvim on macbook with M1 pro - my CPU goes to 100% and it's not usable, even jetbrains works faster.

I thought it may be LSP, so I've removed flutter-tools and configured LSP manually, but it works well, so I assume that something else may make such problems

I am quite new to neovim, just around week of experience, I'd be happy to hear where to search for issues (on my other machine with windows + WSL it works well)

My config: https://github.com/marosiak/lazyvim-go-dart

I've confirmed that it's Mac related problem (probably it's about architecture) - because on Windows thru WSL with Ubuntu it works perfectly

By any chance, do you have bufferline plugin installed ?

I was also facing a huge slowdown as soon as I enter a dart file. Profiling with Snacks.profiler, I found gitsigns and bufferline are taking too much time.

Disabling them improved the performance.

My theory is that this plugin is causing too many redraws of bufferline, due to which the system appears sluggish.
I haven't tried to figure out what it is yet.

EDIT: Setting the lsp log level to debug ( =vim.lsp.log.set_level(1) ) and checking the log file ( :e ~/.local/state/nvim/lsp.log ) shows that there are way too many publishDiagnostic events.

EDIT: The high CPU usage disappeared after I ran flutter update or flutter analyze once
