Using the improved raster graphics handling for square cells with image() rather than spplot() and useRaster=TRUE - equivalent to image.SpatialGridDataFrame() and useRasterImage=TRUE with the same matrix takes 1.2 seconds on x11/cairo. You didn't say which version of R you are using - the raster graphics facilities have been improved recently.
2.14.1-1 on Debian testing.
Did you try using image() instead of spplot() if your cells are square, and if rasterImage() is available in your version of R?
Yes, image() is resonably fast, but misses automatic legend, etc. Thanks a lot for your reply.
