[jdev] Average stream content?

[Guus der Kinderen]

Is there any information on how an average stream is composed? I'm aware 
that these numbers won't represent a lot of specific domains, but I'm 
looking for a general idea, to be used in benchmarking a server.

Ideally, I'd like to have information like this:
x % of all stanzas received are messages, average size q bytes,
y % of all stanzas received are presence, average size r bytes,
z % of all stanzas received are errors, average size s bytes, ...
