JabRef version

5.9 (latest release)

Operating system

Windows

Details on version and operating system

Windows 10 22H2

Checked with the latest development build

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

When opening a big library (45974 items), the memory usage of JabRef goes up to 1.6 GB RAM .
Is this normal or are there memory problems?

When opening 2 big libraries at the same time (45974 items) and (134352 items), the memory usage is at a whopping 2.4 GB RAM.

JabRef running without any library uses 960 MB RAM on my Windows PC.

• So it goes from 960 MB -> 1.6 GB for a library 45974 items
• it goes from 1.6 GB -> 2.4 GB for another library of 134352 items (opened at the same time)

Also when those 2 big libraries are opened at the same time, JabRef becomes slow when scrolling the entry list of the library. When JabRef is running some minutes on the libraries, the slow scrolling dissapears after some time

Is JabRef not designed for those kind of big libraries or is this a problem in the code I found?
