impatient.nvim VS vim-startuptime

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.

That is native and inbuild but I would suggest below options instead 1. Using lazy's Profile tab instead https://github.com/folke/lazy.nvim 2. Using a dedicated plugin to do this https://github.com/dstein64/vim-startuptime. 3. Using an external program hyperfine is one that I use https://github.com/sharkdp/hyperfine

This plugin https://github.com/dstein64/vim-startuptime

dstein64/vim-startuptime (which I never use, my startup time is under 130ms, which is sufficient)

Use the plugin with the flag --tries 100. Also, what are the first 10 lines of output from running the above command? I'll start.

only today I tried this plug to test startup time and got this result:

dstein64/vim-startuptime: ⏲️ A Vim plugin for profiling Vim's startup time.

Using vim-startuptime to profile, I get these startup numbers on an Apple M1 Macbook:

Oh sorry, I already solved my issue but forgot to delete the post! But to answer your question: Of course! It's https://github.com/dstein64/vim-startuptime. You can either launch nvim with nvim --startuptime outputfile.log FILENAME to get detailed diagnostics in the file outputfile.log or just call :StartupTime after nvim/vim has started up to get this graph. It's pretty neat and easy to use!

You could try to install this plugin temporarily : https://github.com/dstein64/vim-startuptime
