Re: [udig-devel] render performance
|
Hi Vince,
Points do not use the optimized shapefile renderer so are slower
compared to lines so that may be the problem. I had thought that the
normal renderer would be good enough for points but perhaps I was
wrong. I tried it on a 1.6 Mhz AMD and it took about 7 seconds. I
admit it is a little slower than I would like and I'm sure it could be
improved down to about 4 seconds without too much difficulty. Is that
what you'd like? If so please file a bug report with the JIRA bug
track, (or ask me to)
Jesse

I've now tried this on another (slightly faster) machine -- it still
takes close to 10 seconds to render all the 100000s of points (this is
after several renderings, so Eclipse should have loaded everything it
needs). If I change the render style away from the defaults (to draw
smaller squares with no outline) then I can eventually get the render
speed down to 3-4 seconds.
Can you explain what setup you are using? Is this with standard uDig
1.0.0, run as a standalone application?
Vince.

It doesn't it takes 3.24 sec on an initial run improving thereafter
due to Eclipse loading techniques,on similar hardware. Maps taking
that long to load are typically the size of the road network of
British Columbia a somewhat larger system, you can down load this as
an example from Geobase.org. I can find no evidence of heap space
exhaustion perhaps you have an environmental issue?
