[udig-devel] UDig Rendering Performance

[Emily Gouge <egouge@xxxxxxxxxxxxxxx>]

I've been developing an application using uDig for a mapping component. 
 I had been using a checkout of uDig from the beginning of the year.  I 
recently updated to the lastest source code to grab a variety of bug fixes.

However, since upgrading the rendering performance of maps is lousy.  I 
loaded the country's shapefile into udig.  With the old version when I'd 
pan and zoom it would be almost instantaneous to re-render.  Now it 
takes between 1/2 to 1 second.  It gets substantially worse if I add 
layers (with 8 shapefiles its taking upwards of 5 seconds to re-render).

Has anybody else noticed this or have any ideas why this occurs?  I 
don't have profiler to run to see where the majority of time is being 
taken up.

Thanks
Emily
