UML tool in Netbeans is very slow

Well I finally decided to document some of the java classes in Model Manager.

I failed.

It appears Netbeans has a performance issue as the UML projects get larger the responsiveness of netbeans gets worse.

I had to submit this bug against Netbeans.

For some reason each click in Netbeans triggers a scanning of the XML document. As this document gets larger the scanning gets slower. Never mind the fact it only uses 1 of my 4 cores.

I looked into the actual UML project and the etd file is over 32 Mb. No wonder it takes a while to scan.

Edit: the issue has been fixed in Netbeans 6.1 beta version.
