My Neovim takes roughly 113ms to fire up. THIS IS FAST. However, I don’t lazy load anything. Being a Lazy.nvim user, it’s kind of a shame I’m not actually making use of my plugin manager's flagship feature. But then again, it takes 113ms for nvim to start, what is there to gain here? Let’s say I drop it to 50ms. Still reading? GOOD. You’re as crazy as I am, let’s speed things up! The Slow Startup StruggleThere are a few factors affecting startup times:
0. Lose redundant plugins!This cool plugin dropping your code on the ground like sand? Not helping you in the 99.99% times you’re not showing it off to a colleague. Don’t ask me how I know.

Use them to load plugins only when needed. For example: Learn more about optional events with 4. Optimize the Heavy HittersFound some other plugins eating up time? Let’s tackle them:
5. Let me confuse youLazy loading isn’t always the best approach for every plugin in your system. While it can improve initial file opening times, it may introduce latency when you start interacting with the file and delay the appearance of diagnostics. Consider the user experience:
With this approach, you’ll slash startup times without sacrificing your favorite Neovim superpowers. Thank you for reading, as always, feel free to reply to this post directly with questions and comments! |
