In my opinion, you are trying to force pstricks to do something that is not naturally good at---large data sets and/or floating point operations. If for some reason you wish to be able to get final output with pstricks, try generating the plot (no axes or labels) in, eg, gnuplot with output to an eps file, then import the graph to a pspicture and add the axes and labels with pstricks.
