Could you check current SVN again and see how it works?
I've sped up zlibstreams and it's now saving memory on the read, at
about a 12% drop in speed, now I think due to the overhead of the
single extra function calls on many small reads.
I'm unsure whether I want to leave zlibstreams in. It has the
advantage of making skipping variables much faster and more memory
efficient, and maybe some increase in memory efficiency as the
variable is read, but still, the small performance penalty is
