Now I'm curious. What is it that makes Solaris<->Solaris performance good despite the TCP breakage? If the server always advertises a tiny window, performance ougut to be equally bad when talking to Solaris or FreeBSD. I've seen threads about this problem before on the lists, and I don't recall anyone coming up with a real answer.
