Good hint! It didn't solve the problem but provided more insight.
My batch size was unspecified (default 500). I tried lowering it to 50, and
the problem was still there. But now I realized that once I have scrolled
all the way to the bottom (of the batch), it becomes fast thereafter!
Apparently there is some information fetched on demand when one first
scrolls to a page, even within a batch. Once that has been fetched, it is
remembered and future references will be fast.
Probably you have an idea what it is doing here, what kind of information it
is fetching on demand. Perhaps this is caused by an underlying Hg call being
slow. If that's the case, perhaps this information could be fetched by a
background thread. Usually the display is visible since a couple seconds
before one tries scrolling or searching, so a background thread could
utilize that time without adding further wait time for the user. But I'm too
far ahead speculating. Should wait for your assessment.
