In addition to what Paul wrote, check the following (assuming you are using netCDF4 to read the files; the same may apply when using other netcdf interfaces): Use slicing to extract the variables you are plotting as ndarrays rather than trying to call mpl routines with the netCDF4 variable objects themselves. I haven't tracked down exactly what is happening, but I have noticed that extracting and plotting can be orders of magnitude faster than feeding the netCDF4 variable directly to the mpl plot command.
