The STREAMS stuff never performed well

Larry is being polite. It sucked.

It was never designed for it. dmr designed Streams to replace the tty handler. I never understood why the Summit guys insisted on forcing networking into it.

and the BSD TCP stack or something

like it went into Solaris at some point.

Right. This is one of the places where SVR4 != Solaris

I was researching a book a long time ago and looked at this. I had Solaris, SVR4 and some other stuff at the time. Like you bit rot has long set in on the details, but I do remember that the primary thing that Solaris had was support for Sun's threading model and the networking code had to be a first class citizen or it was not going to scale.
