If you are trying an isosurface or volume display, I could understand this. The computations for that using radar data are intense. We will be working on improving the performance for these radar displays in the future. For now, I would stick to sweep, CAPPI and RHI displays. You can increase the amount of memory allotted to the IDV by modifying the runIDV script. Change any occurance of -Xmx512m to -Xmx1024m.
