Are you required to use PNG or could you save the files in an alternative lossless format like TIFF [1]? If you're stuck with PNG, mtpng [2] mentioned earlier seems to be significantly faster with multithreading (>40% reduction in encoding times). If you're publishing for web, TIFF or cwebp might also be possibilities with -mt (multithreading) and -q 25 (lower compression and larger filesize but faster) flags, or an experimental GPU implementation [3].
