Sampling the command line tool when processing files shows it is spending 90% of its time writing the png file of which most of this time is spent in a function called deflate in libz. The final file quality is good. I'm using CGImageDestination to export the file with default settings.
I’m a little unclear here. Are you saying the process appears to much slower than you can reasonably expect? Or simply that you’d like to find a way to make it go faster? (something which may well not be very possible)
