Again it boils down to design  WCF  C# can process  over 22000 small messeges per second on an average 2 year old quad server.   http://msdn.microsoft.com/en-us/library/bb310550.aspx#wcfperform_topic4. This is more than sufficient for most applications especially as with eventing systems you can add servers relatively simply , the algorithms which manage  the propogation of  subscriptions and the path are far more important .
