Created attachment 120101 [details]
the file whose opening is very slow

I experienced a regression since the version.

I could open the attached file faster with the previous version of Libreoffice.

With version, it requires now 87 seconds (~10 times more ?).

3 other users of my office experienced the same issue (didn't ask to more) with the same OS and hardware.

I have a fix for this one and related conditional format performance problems.

Let me see how well it works and if I manage to find all bugs that I'm most likely going to introduce.
