Hi Christopher , thank you for the reply. I'm not surprised about 100% cpu usage, I'm surprised about 100% cpu in combination with only 40 MB of ram allocated when I have 2 GB shapefiles. I would only be sure that everything is working ok and that there isn't some problem that I can't see...
Is it normal only 40 MB allocated with 2 GB of shapefiles?
