Unfortunately, ChunkyPNG is pure Ruby so it will always be relatively slow, especially for large images. In order to resize an image, it first needs to be loaded, so that is not going to help if you don't want to use RMgick.
Did you enable oily_png already? It replaces some of the slowest algorithms in ChunkyPNG with native/C implementations, making image loading and saving an order of magnitude faster. See https://github.com/wvanbergen/oily_png
Hope this helps.

Thank you!!!
it took to compare two pictures of 1 mega like 70 seconds and now... 9 seconds!!! :)
I'm taking a look at other libraries to see if it helps to resize the files before comparing them
