I'm wondering... just how much of a load is a single SoapUI instance on a given machine capable of generating? And how would you measure such a thing? In, say, SOAP envelopes/sec?
This is one of those "how long is a piece of string?" sort of questions, of course. But I'm wondering, in the absence of a server capable of comfortably serving responses faster than SoapUI can dish out requests, how you'd establish it?
