performance yak shaving

[boehs]

Hi, I was doing a little cpu profiling as one does when they have nothing better to do,

dev server

and I noticed that 11ty seems to be burning precious milliseconds on loading the development server even when the serve command is not called.

I noticed that 50-60ms appears to be in (anonymous server.js:1) (file:///Users/evan/Code/site/node_modules/.pnpm/@[email protected]/node_modules/@11ty/eleventy-dev-server/server.js:1:1)

The command I did was node --cpu-prof ./node_modules/@11ty/eleventy/cmd.cjs --quiet, so no dev server should have launched, and indeed none did, but node still spent time loading it due to the top level import. await import(ing would save 50-60ms or so. Amazing!!

micromatch and fast-glob

it appears 11ty is using two glob libraries for some reason? each one of them takes between 10-15ms to load, so that much would be saved by only using one

maybe the micromatch direct dep can be removed but it won't impact perf because fast-glob uses it

thank you for attending my ted talk. god bless 11ty.
