For my case, as my project consists of 30 modules, the first start up of Netbeans 7 become painfully slow after I upgrade to Java 7 and then upgraded to Netbeans 7.2.

As I found out from googling, it is due to memory issue and can be fixed by modifying netbeans_default_options in <netbeans>/etc/netbeans.conf

-J-Xmx512m -J-XX:PermSize=64m  (add any one or both as necessary, or change the value accordingly)
