I updated Jabref from v3.8.2 to 4.0 and have problems with it starting up extremely slowly. The interface eventually comes up, but only after several minutes.
Downgrading to 3.8.2 immediately has it all running smoothly again.
This is on a Win 7 and on a Win 10 machine. I did upgrade to the latest Java RE.
Are there any suggestions what I could try? Right now 4.0 is essentially not usable for me.
before you stick to 3.8.2: We are working on improving the performance massive. One contributor already submitted one PR which got merged in the current dev version. Another PR with great performance improvement is on its way.
