> Ojan, thanks for doing this investigation! I think this is good news actually.

I agree. The ideas in bug 6274 seem likely to address the perf issue. Sorry to
be a broken record, but, is there anything we can do in the meantime about the
perf and/or memory regressions?

For the perf regression, can we just delete the canUseGlyphCache changes? Then
we'll get to fixing the bug in a way that doesn't cause a perf regression
without leaving a perf regression in the tree in the interim.

I don't know what to do about the memory regression. Enrica mentioned the idea
of tweaking the size of the glyph cache. That seems reasonable to me, but I
don't have a sense of the tradeoffs involved there.
