Probably the easiest is to use the ChunkWorx plugin, let it generate some 30x30 chunks, measure time. Do this for both versions, making sure that the chunks are at the same coords (if you're comparing raw code speed (as opposed by comparing different generators), make sure the world.ini is the same, too) and use a different world folder for each, so that the chunks actually generate, instead of being loaded.
