Reduce Neovim startup time with plugins
You could use impatient.nvim or the new vim.loader module if youβre on nightly. Both work really well. I used impatient for a long time and it reduced my startup time by half. Iβm using vim.loader now and it reduces it by about the same amount
-
Optimizing my startup time
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 isnβt 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 .
-
lazy.nvim is amazing!
automatically caches all startup code before :h VimEnter or :h BufReadPre (basically what impatient.nvim does)
-
fzf is so powerful when you use it well ! code/files/tags/git history
there is an amazing plugin called impatient.nvim that cache a lot of stuff and make other pluggins go so fast !

Guide: Structuring Lua plugins
:lua vim.pretty_print(vim.mpack.decode(vim.mpack.encode({some = { thing = false }}))) used by impatient.nvim
- Can neovim config be baked in to make neovim blazingly fast?
-
Default mappings override user mappings in Rust ( [[ and ]] mappings )
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:
-
what is your startup time like?
Are you using impatient.nvim? It caches lua modules. My startuptime with 72 plugins (including it) and zero lazy loading is 600ms.
- Why do Neovim users actively seek out lua rewrites?

Having the worst time trying to use JDTLS
I recommend that you do not configure jdtls like the other language servers, it is better to use the nvim-jdtls plugin.
-
Noob here, would neovim work for my usecase
Java is actually pretty good with Neovim, jdtls and this plugin. One of the best language servers and I'm using it on a regular base with medium to large projects, mostly spring-based. No Android though.

Does anyone config java for neovim?
Sure. Any server that lspconfig supports will work. But for java development is better if you use nvim-jdtls. The documentation in lsp-zero has a guide on how to setup nvim-jdtls.
