best functions runtime for performance and stability

I have a ton of functions performing tasks, big and small, like user signup document writes, cron db cleanup jobs, essentially all writes on the database are mostly via functions with users not writing directly to DB via SDK.

I currently am using dart runtime for functions but I have seen issues like function failures and timeouts. With recent addition of Go got me thinking how much of a performance different would it make ? Would it make sense to migrate certain intense functions from dart to Go ?

Has anyone done any performance testing who can share results ?

Are you using appwrite cloud?

I think currently Dart is one of the most performant runtimes. If you are self hosting, you should scale the containers and set the variables in order to run them concurrently and achieve better performance.

For example: _APP_WORKERS_NUM
