Jabref 5.0 very slow update gui entries

I upgrade jabref from 4.2 to 5.0 today. Compared to version 4.2 the version 5.0 responds very slow in the order of 10sec to update a changed gui input.
How can I improve the performance?

Same for me here, slow gui (OS: Win 8.1)

Sorry for the inconvenicences. This is partly related to the new UI technolgy.
We are planning on performance related optimatzions in the next release.

After some attempts with different Jabref versions (4.3.1; 5.0 and 5.1) I found a solution at least for me.
To override the old version, i.e. using the same old folder folder (c:\Program Files\JabRef) showed no progress, still to slow (except of jabref 4.3.1).
In a next step I removed all previous jabref installations and subsequent installing jabref 5.1 from scratch I’ve got a system which now is what I expected fast enough.
Therefore I assume that my previous jabref installations contained some faults.

I updated jabref to development version 5.5 build 3/22 (yesterday). Jabref is still very slow with a lot of typing lag time.

I am on windows 10 64 bit.

Would appreciate any guidance.


First of all I’m just a user. Not a developer. I’m wondering where did you get the development version 5.5 build 3/22. The only version on https://builds.jabref.org/master/ is 5.1 from 23.03.2020. (status 24.03.2020)
All I can say my approach is described above.

  1. removing old jabref version
  2. install from scratch version 5.1 from 12.03.2020

JabRef 5.1–2020-03-12–23034ce
Windows 10 10.0 amd64
Java 13.0.2

Hope this helps

Thanks. I meant 5.1.

JabRef 5.1--2020-03-22--0808168
Windows 10 10.0 amd64 
Java 14

I did fully clean out the earlier installation.

Still things are slow.

I was wondering if others are also seeing this behavior.

This is more a question for the developers.



we are aware of some perfomance issues with large databases.

We are constantly working in improving JabRef and tweaking the performance.

Thank you. Appreciate all the work.
