Description hajue 2006-07-10 14:54:38 UTC

Generating a web report was a nice feature in NetBeans 5.5 preview. The 
reporting was done within few minutes. It was only a deficit that one could not 
zoom in (and out) the diagrams.

In NetBeans 5.5 beta the web report slows down to two diagrams per hour. It 
seems to me that the .jpg generation for the zooming functionality (5 jpg files 
per diagram) takes most of the time.

My UML project consists of 
- 13 class diagrams,
- 6 packages,
- 28 classes,
- 9 interfaces
- and some datatypes.
The web report doesn't succeded within 8 hours.

Hi hajue,
Can you specify the way you access your system(local/vnc/remote desktop)?

Comment 2 hajue 2006-07-10 16:20:14 UTC

Yes, well, we access the server via WRQ ReflectionX v11 and a 100 MBit/s LAN.

Comment 3 Sergey Petrov 2006-07-10 17:15:47 UTC

ok,
I thought it's in release notes, but i prefer to think it's a bug in any case,
let it be opened for now :) until release noted or fixed,
You can apply workaround for now:
go to <ide_installation_path>/etc/netbeans.conf and add
-J-Dsun.java2d.pmoffscreen=false
flag to netbeans_default_options. You'll get impovement in some uml actions but
it may result in less overal netbeans perfomance.

see also 78312, I don't like to close this one as duplicate for now becase I
think first one should have higher priory or at least be documented.

and see alse 78290

Comment 5 hajue 2006-07-11 09:55:17 UTC

Very well, with the given parameter the report generation lasts less than 7 
minutes now again (of which 4 minutes are needed for the JPG construction).
