Bug#750785: Slowness with context and xetex
Hi Hans, hi Taco,
(please keep the Debian bug report in Cc)
We got a report here at Debian that context when run over xetex
is extremely slow, which I can confirm.
It is interesting that when I drop the original TeX Live (not Debian)
xetex into our /usr/bin, then it is getting fast again.
On the other hand, I don't see any slow down when running
xelatex on a similar document. The test document is a simple
\starttext
lots of lorem ipsum in paragraphs
\stoptext
If I change this to a simple latex document {article} it is also
very fast.
So that points at something that context is telling xetex to do/load
that exhibits a bug, but I have *NO* idea where the bug might
come from.
The difference between TL original and Debian is that we use
shared libraries. For pure text processing the fault should be
in harfbuzz, right? We are having 0.9.28.
Do you have any other ideas how to track such a bug? Do you have
any guess what could it be that context tells xetex?
Thanks a lot
Norbert
