Yes, I'm talking about segment size. When I looked at the mse code (a
while ago) and contacted you with about it, it seems like you were using
the same miniscule segment size as FPC did. Now FPC uses 65535, which
speeds up blob operations significantly.

Splitting things up in segments of course increases network traffic and
may not be handled by fb efficiently (I've posted links to my
requests+resonses on the FB list)... but it's up to you of course.
