It's interesting to see the intersection between Deno TypeScript code and native Rust libraries, e.g the native HTTP library [1], however it would be interesting to see a performance evaluation between this and a regular express app.
On many of our internal benchmarks, Deno's std/http server outperforms Node's http (so express/koa too). There's still some room for improvement on our end and we would like to put together rigorous benchmarks before sharing that broadly.
I am very interesting in the performance implications here as their _has_ to be some performance tradeoffs given you have to serialize / deserialize across the bindings. I get that Rust is fast, but at what point does the trade-off no longer make sense?
