Thanks, that thread (and your summary) explain the source of the
problem, namely that small changes to a big file will yield small or
large delta
files depending on where in the client file the changes are located.

Is there any simple way to bump up the window size, say to 100 MB or so?
Our server has gobs of RAM and it really bugs me replicating the 50MB
text file every day even though the actual changes are quite small. I'd
be
happy, if need be, to tweak some #define and recompile, if it is that
simple. Or does the delta-window size somehow escape server
encapsulation into the client server protocol? Or some other problem?
