Help needed with connections per second
I think we are doing something wrong. Currently we have a running ratchetphp websocket over SSL and it can only handle around 15 connections per second and starts to have (more) problems when reaching 9000 concurrent users

The code works like this:

- on construct we enable logging (syslog) and create an SplObjectStorage to store the users
- onconnect we 
  - validate the token via an **external** api (using a guzzle client)
  - add the result to a SplObjectStorage object

Should we move the validation somewhere else? Since it is an api call won't be superfast.
Messages are sent pretty quickly even on times we have a lot of load the cpu/memory isn't the problem.
