[udig-devel] render performance
|
I should say I'm new to udig, although we have used geotools (and openmap,
for that matter) in the past. We're currently evaluating what GIS/mapping
tools to use for a variety of projects, and we make heavy use of Eclipse
RCP, so an obvious thing to do was to test uDig 1.0.0.
My first test was to open the workspace and create a new map with a couple
of shapefiles generated by a route optimizer we use. I tried to zoom in
and out and pan and select things, and found that on each such action the
progress bar for rendering sprang into action and only after 2 or more
seconds was the map view updated. (This on a relatively fast machine).
In addition to this, certain lines in the shapefiles were not clipped
wrongly when zooming in (i.e. they should have been drawn, but weren't).
So, I have to ask, what performance expectations are there for uDig? Are
there known bottlenecks? Is it expected that rendering should (a) take 2+
seconds, and (b) continue to take so long just for minor events like
panning, selecting, etc?
For those interested, I've placed a .zip file of the 2 shapefiles here:

thanks for any insights!
