How to reproduce:

1. Have a large bibliography. E.g. 100 000 entries.
2. Select many entries via holding Shift + PageUp

Preferences that might lead to performance improvements/degradation: (Note: for other known causes for general performance problems, please check GitHub issues with label "performance"):

I am not completely sure (yet), which of the following preferences has the highest performance impact on selecting entries. I disabled all of them at once and had the feeling it allowed me to select entries maybe 50 - 70% faster? But that was just my gut-feeling.

1. Options > preferences > General > Collect and share telemetry data to help improve JabRef
2. Options > preferences > Groups > Display count of items in groups

3. Enable options > preferences > Entry table > Format of author and editor names: e.g. Show Lastname, Firstname Workaround: Disable this preference for performance gain by switching to Show names unchanged

   To do:

   • [ ] do some proper measurements with stopwatch.
