⚡ Profiling & Debug

Great care has been taken to make the startup code (lazy.core) as efficient as possible. During startup, all Lua files used before VimEnter or BufReadPre are byte-compiled and cached, similar to what impatient.nvim does.

My config for example loads in about 11ms with 93 plugins. I do a lot of lazy-loading though :)

lazy.nvim comes with an advanced profiler :Lazy profile to help you improve performance. The profiling view shows you why and how long it took to load your plugins.

See an overview of active lazy-loading handlers and what's in the module cache.
