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. |

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.

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?
