One of the easiest ways to lose performance is to do lots of
byte-at-a-time operations when you could have just as easily read lines
or whole buffers-full or whatever. For 8.0, we've changed around the
character stream stuff to be buffered (rather than the unbuffered
approach used in 7.x); that one change reduces character-stream overhead
by a factor of about 3-4.
Right. I looked long and hard at doing this for 7.0, but the stream
protocol was too much of a mess, and it was going to be hard to do
without the different layers of buffering conflicting for message names...
Have you organized (not reorganized) the stream protocol? It *really*
