It's very hard to bibisect this. I am getting from 5,6-10,11 seconds, nothing relevant with 7.4. Couldn't be here used an automated bibisect with time and ./instdir/program/soffice and to use good or bad depending on seconds?

There are a lot of bugs to bibisect which have performance problems, and it's hard to detect the differences. I had 5 seconds, than 10 seconds. But maybe just happened.
