Version 5.0 of JabRef is extremely slow on my Windows machine. It takes mabye 30 seconds to start up, and then, when I'm typing an entry comment the lag between when I hit a key and when the key shows up in JabRef is excruciating.

• This is after rebooting, etc. to see if anything else was slowing down my PC
• my bib file has 2127 entries
• I didn't notice this slowness in JabRef 4.x
