From the attached snapshots it looks like a problem in org.netbeans.modules.maven.options.SettingsPanel

not really maven issue. as can be seen in the screenshot, the vast amount of time is spent in classloading (and IO down the road/stacktrace)
Comment 4 Milos Kleint 2012-06-04 12:12:17 UTC 
reassigning back
Comment 5 Theofanis Oikonomou 2012-06-04 12:37:38 UTC 
true. Thank you Milosi. It seems that the majority of time is spend opening a ZipFile (heavy disk load?), so nothing that can be done from options side.
