Hi Arnd, I haven't worked with large point datasets much. What it is exactly that is slow? Is it redraw time? Or perhaps the particular operation that you are doing?
I know that point layers do not benefit from the recent decimation optimization, so they take longer to draw than equivalent polygons and polyline layers. I think Michaël tried a point decimation optimization, but wasn't satisfied with the results. regards, Larry Becker On 10/1/07, Stefan Steiniger <[EMAIL PROTECTED]> wrote: > > mhm > from my point of view it is both OJ and JRE.
