--- Comment #9 from Aleksei Nikiforov <darktemplar at basealt.ru> ---
I've ran bisect and this is my result:

8a800eea613c0f5ad3302136766791dc58880fb3 is the first bad commit
tdf#104425 sw: split rows w/large min height (fix layout loop)

https://cgit.freedesktop.org/libreoffice/core/commit/?id=8a800eea613c0f5ad3302136766791dc58880fb3

I've confirmed that if I revert this change on current master (there are some
revert conflicts which needed to be resolved), attached files are opened almost
instantly now, while it took minutes and tens of minutes before.

I guess reverting this change for LO might be not an option, but at least
adding a configuration option allowing to choose between correct table
formatting and fast table formatting might be a good idea, unless performance
can be fixed for current implementation. I didn't look into performance issue
in this change yet.
