Performance differences between different web socket clients

[amadrian]

First of all, thank you very much for the awesome library!
We have recently integrated in to our app that is being used by more than 70 million users and it is going strong!

Now to the topic:
Is there any plans to add benchmark including different web socket clients (Built-in, ktor, etc) to see how they perform?

The reason I am asking is that we are seeing huge differences in our prod app in terms of 95th percentile performance between iOS and Android.

Our set up:
iOS -> Using Built-In Darwin web socket client
Android -> Using ktor with okhttp as web socket client

Observances:

• iOS' web socket level connection performance is 250 - 300ms faster than Android at p95
• iOS' STOMP connection and STOMP subscribe performance is ~50ms faster than Android at p95

Measurements taken using Firebase Performance SDK. Sample size is ~500k.

Thank you very much!

Thank you so much for your kind words, that's very encouraging!

Regarding benchmarks, it would be a great idea. I don't have a lot of time to invest in benchmarking right now, but definitely worth considering.

Out of curiosity, have you tried using the Okhttp implementation without Ktor in the middle? Maybe the extra layer of conversions slows things down a little.

Not yet but we are considering it at the moment. I'll update here if we have any success.
