Usage with Vite performance question

[Neevalt]

Hello,

I wanted to give a try to lightningcss on my Vue project using vite. However, using Vite's debug tools, I see that the CSS part of my components is taking actually longer with lightningcss vs postcss with the vite:plugin-transform.

You can see it in action here : https://stackblitz.com/edit/vitejs-vite-veyt6b?file=vite.config.js&terminal=dev

Just change the vite.config.js file's css.transformer from lightningcss to postcss, then run DEBUG="vite:plugin-transform" npm run dev.

However both are quite "slow" on stackblitz, the difference is quite drastic once the project is cloned on my own machine (as in, vite:css takes ~0.1ms with postcss, and around ~30ms with lightnincss).

Any idea why that difference is and if it can be adressed ?

Thank you in advance 😃
