My concern is either that QuickJS is something like 100x slower, or that even when using Deno, the download experience will be insanely slow.

In my mind, an acceptable time for users might be 30 seconds (somewhat similar to watching an ad). If QuickJS is taking >20 minutes, then it is some 40x slower? Seems very high?

> QuickJIT (a fork of QuickJS that uses TCC for JIT) might yield better results, but still slower than Deno.

Interesting, not come across it before. Running C code seems like an insane workaround from a security perspective.
