Only recently, my Freemind program has become extremely sluggish and unresponsive (big lag) when moving my mind map around. I use Arch Linux with xfce4. Freemind is made with Java. If I move the mind map around, the X process shoots to 20% CPU, doesn't seem a lot but something between X and Java programs are really bringing their performance down.
I can barely use Freemind now. Freeplane is also affected.
I noticed if I keep the Freemind window really small, it's responsive. If I maximise it, everything slows down within the application. Adding new notes, or move the map around, shoots X to a high CPU and there is a 5+ second lag in anything I do in the app.
Is there anything I can do to improve performance? It's only started recently, everything is up-to-date.
