--- Comment #46 from Noel Grandin <noelgrandin at gmail.com> ---
comments from vmiklos:

<vmiklos> noelgrandin: without reading the bug; IIRC the footnote parsing is
lame, and it parses the whole stream all the time, but ignores all but one
entries; so you have perf problems when you have lots of footnotes, correct?
<noelgrandin> vmiklos, correct.
<vmiklos> noelgrandin: one high-level idea might be to see what the RTF
tokenizer does, i think it already generates a token stream which doesn't have
this problem and handled by dmapper. if this is indeed the case, then perhaps
the writerfilter/source/ooxml/ code could be improved to do the same, that
might solve the problem.
<vmiklos> noelgrandin: or a different way: see if comments have the same
problem; if not, perhaps the solution used there could be applied to footnotes,
too.
<noelgrandin> vmiklos, thanks
