Well, there is one thing that you could do with your 6.1.3 version, but it is a
bit complicated. It would be taking a callgrind trace that will allow
developers to see, what calls in the code are taking the most time.

The Ubuntu ppa for 6.1.3 offers debug symbol packages, which you need to
install:
https://wiki.documentfoundation.org/QA/BugReport/Debug_Information#GNU.2FLinux
I checked here that the -dbgsym packages are available:
https://launchpad.net/~libreoffice/+archive/ubuntu/libreoffice-6-1/+packages

Then you need to install the valgrind program (I guess just sudo apt-get
install valgrind).

Finally, you need to follow the steps in the section "GNU/Linux: How to get a
callgrind trace" in the debug info wiki article.

For the actions to perform, I think it would be enough just to move a single
element and then quit.

For compressing the callgrind.out. file, tar.xz seems to be the best choice (of
the commonly available compression formats).
