Has anyone built something on Cloudflare Workers with Kotlin? Any gotchas or anything I should look out for? :pray:

I did. Few gotchas, yeah, but overall it works well

Feel free to post any issues you have. I may be able to help

We found that using kotlin adds a massive delay (100-200 ms.) on ie. page rewriting so we had to ditch it

Its hard to debug workers (especially timing/performance as `Date()` is faked) but it seemed like it was just the initialization cost of the worker that had to be done for every request.

Auch. 100-200 ms is huge in the context of a Worker env

<@U1JP5M6LU> Kotlin adds a 100-200ms delay compared to .... ?

It takes time to load coroutines, stdlib and whatever it needs

I think our plain javascript implementation that just uses promises adds like 2 ms.
