How scalable are websockets with Pedestal and Jetty? Is it fully "non-blocking"?
found my answer, seems to be based on nio and some issues with blocking behaviour was resolved by e.g send-async and more functions.
@jarvinenemil keep in mind that you have full control over how websockets are implemented. You can provide your own start fn, listener implementation if you have specific needs
thanks, i'll keep that in mind
