Jabref is extremely slow on MacBook Air with macOS 10.14.5 (18F132)

Hello, I’ve downloaded Jabref for macOS but I can’t use it because it’s extremely slow.
I thought that this was a Java problem, but I tried with both Java SE 12 and Java SE 8 without any success.

How can I solve this problem?

Thank you in advance.

Which version of JabRef do you use? The latest development version includes a few huge performance improvements.

Hi, I’ve downloaded the latest version, but the problem still persists…
