Hi,
One remark about memory consumed in OJ. When I load a shapefile with 36 580
polygons (size 18 mb) the memory using by my java virtual is up to 202 mb.
If I minimize my OpenJUMP windows and I open

If I minimize my OpenJUMP windows and I open it again the JVM display : 85

Hi Stefan,
1. Is there somewhere I can get a copy of the shape file to test with?
2. Is the speed up working for other large shape files?
3. Does it perform better if you zoom to full extents instead of using the
Zoom bar.
4. What is the Committed Memory showing after you load the file?
5.

Hi Stefan,
It occurs to me that I never use the Zoom bar so I probably haven't tested
it. The Zoom bar does a more radical kind of decimation simplification
itself. It might be interacting with the Java2DConverter decimation in a
bad way. I'll check it out.
thanks,
Larry

Hi Stefan,
I seem to be duplicating the Zoom bar behavior you reported without the
speed mod. If I click and drag the zoom bar slider, I get very slow redraw
times on the order of ten seconds, however If I click the zoom bar it is
faster. I think JUMP is starting multiple render threads
you are right.. if i click on the zoombar.. then everything seems to be
faster(=normal) with my modified version.
I actually see the slow behaviour too if i move the slider with an older
jump version and a jump-i18n version (which is a bit odd, since the
other version i did test for comparing
11 matches
