Jason, Actually it was far slower a year ago. Big progress was made cutting down memory use and related actions, which speeded up the IDV. I do not know if more big improvements are possible. The drag is not Java per se but the 3d visualization code we use which is very complex. It is used even when doing 2d plots. Most of us here are using Intel processors with speeds over 1.5 GHz. But I was using 500 MHz to develop the IDV until last month. RAM is essential for faster performance; 500 meg is about the lower limit for no bottlenecks. That depends on the data and displays you use of course. You can see the present/max memory use in the bottom line of the IDV display window. You can see multistation 3D Profiler plots in the current IDV, along with grided output.
