impatient.nvim VS nvim

You could use impatient.nvim or the new vim.loader module if you’re on nightly. Both work really well. I used impatient for a long time and it reduced my startup time by half. I’m using vim.loader now and it reduces it by about the same amount

The 20-30 ms promise depends on your hardware. In my case, vanilla Neovim takes about 18 ms to startup, so a realistic good startup time for my config is around 50-60 ms. Lines of code isn’t a great reference either because you could just lazy load a bunch of plugins and have more LoC but still better startup times. What I would recommend is using lazy.nvim or if you wanna stick with packer, then pairing it with impatient.nvim .

automatically caches all startup code before :h VimEnter or :h BufReadPre (basically what impatient.nvim does)

there is an amazing plugin called impatient.nvim that cache a lot of stuff and make other pluggins go so fast !

Try installing https://github.com/lewis6991/impatient.nvim first.

:lua vim.pretty_print(vim.mpack.decode(vim.mpack.encode({some = { thing = false }}))) used by impatient.nvim

Did you defined your [[ and ]] mappings in that file or just created it? the after directory runs at the end of your config so you can override this kind of settings. Maybe you are using impatient.nvim? From their README:

Are you using impatient.nvim? It caches lua modules. My startuptime with 72 plugins (including it) and zero lazy loading is 600ms.

So I wonder, how my config could be wrong if everything was ok ? I've always thought I could have the structure I want as long as I require files/plugins correctly, and as I saw this in many people configs I thought it was not a bad practice, more a way to have a clean config, but well, maybe I'm wrong.

There's things that seem strange to me in your plugins.lua. Not sure this is the problem but I've never seen use({something}) like this (I mean with parenthesis). Finally checking if packer exist and install it if necessary becomes useless if you install it later with packadd. There's a quite big config and I think you know what you're doing but seeing these I prefer showing how I did for my config. You can check this capture too if you want.

Nice ! I was searching for something like this. I've been trying to do the same but after 2 hours and so much pain in the config I git restore my config ^

I also hard times moving away from vimL and Coc at the begining but when I realised that LsPinstall/LspConfig just install and configure every lsp servers correctly (you also can reload them once updated if you read a bit their README) I stopped worrying and enjoyed a nvim that never as been so fast and powerful. I can share my config but you surely have better ones in the first link I gave above.
