EnglishIs LunarVim Fast Despite Its Built-in Features?
Updated
Yes. LunarVim is designed so that its feature set does not come at the cost of speed. According to the project, it lazyloads plugins wherever possible, and disabled plugins do not slow it down because the plugin list is compiled with only the active plugins. The stated goal is that you don't have to choose between features and speed. This applies if you run LunarVim as your Neovim IDE layer and keep its plugin configuration intact.
How LunarVim keeps startup and runtime fast
LunarVim uses two related mechanisms:
- Lazy loading — plugins are loaded only when needed, rather than all at once at startup.
- Compiled active-plugin list — the plugin list is compiled to include only the plugins you have enabled. Plugins you turn off are excluded from that list, so they don't add overhead.
The practical effect is that a large built-in feature set (autocompletion, integrated terminal, file explorer, fuzzy finder, LSP, linting, formatting, debugging) doesn't automatically mean a slow editor.
Why disabling plugins doesn't hurt performance
If you don't want a builtin plugin, you can toggle it off in config.lua. Because the plugin list is compiled with only the active plugins, a disabled plugin is not just inactive — it isn't part of the compiled list at all. That's why the project states disabled plugins "will not decrease speed."
What this means for you
| If you care about… | LunarVim's approach |
|---|---|
| Fast startup | Lazyloads plugins wherever possible |
| Keeping features | Ships autocompletion, terminal, file explorer, fuzzy finder, LSP, linting, formatting, debugging |
| Trimming what you don't use | Toggle any builtin plugin on/off in config.lua; disabled plugins are excluded from the compiled list |
| Not choosing between the two | The stated strategy is to avoid trading features for speed |
Who this suits
This matters most if you want an IDE-like Neovim setup with many built-in features but are concerned about startup or runtime performance. LunarVim's answer is that its defaults are opinionated but extensible, and its loading strategy is built specifically so that features and speed aren't mutually exclusive.
For the exact behavior in your setup, check the plugin toggles in your own config.lua and confirm which plugins are active — that's what determines the compiled plugin list and, in turn, your performance.
