Snjezana tend to be good at finding causes, but performance is important for us all, so ask away here in jbosstools-dev and #jbosstools chat. First you should do is grab a a few jstack's of that eclipse when it is freezing and see what is showing up in the stack trace. If that does not reveal anything connect a profiler (jvisualvm might be enough) to spot the hotspots for your case.

Can you move this to jboss.org instead ? Also I still have my same questions that is on that thread ;) And could you show the % of difference + deviance so it is not just raw numbers and a possible misleading average ?
