<GH>This may depend on your test setup. Are you sending between a fixed 
pair of URI:s, or multiple?
Have you considered this rule from RFC 3428? "

    A UAC MUST NOT initiate a new out-of-dialog MESSAGE transaction to a
    given URI if there is a previous out-of-dialog transaction pending
    for the same URI."

So, if you are sending between one pair of URI:s, the sender needs to wait for a final response before sending next MESSAGE. With usual network delays that can mean a maximum of about 5 MESSAGE per second or so.

With multiple URIs on both sides, the figure should be higher.
