Ways to improve performance?

I can't seem to get faster performance than about 1.5 seconds locally and 2.5 seconds deployed to vercel.

It's just some basic text from a custom font, and a few emoji.

All user code including font loading takes 15ms cold and less than 1 hot, so I'm pretty sure it must be rendering or something else.

Thoughts?

Can it be related to the emojis? FWIW .ttf font with only necessary charsets (e.g. Latin) and inlined emoji images (if they are static) will make it a bit faster.

This is interesting. I'll have to look into this

You can analyze what % of time was spent on fetching fonts and images. And then, in general smaller and simpler images (fewer pixels) will be much faster.

Can I do this if I'm using ImageResponse with Vercel? I think it happens behind the scenes.
