Well, we don't have any tests that have both UDP and TCP flows, so for now that won't be an issue. It may be if we add some, I suppose, but there's always the test parameter to override the UDP size? We can also just make it TCP-only, though... -- You are receiving this because you are subscribed to this thread.
