InvokeGroupAsync

[grahamehorner]

the current implementation of DefaultHubLifetimeManager.InvokeGroupAsync scans each connections metadata in the in the hope of find a connection with a matching group; this would result in wasteful resources when a name of a group that is not used/or has no connection is supplied, IMHO the default implementation should have an index of group names with a count of active connections to prevent this especially when a hub could have many connections.

Yes we're going to do this eventually. None of the stack is optimized right right. We're working towards an MVP before we do any of that work. #394

@davidfowl happy to start they ball rolling with a proof of concept if that would help?

[davidfowl]

Sure
