My question is: Do you need all thubnails at once? I setted up a images album for kindergarten for my child with more than 17GB (>4000) jpeg's. I used nginx webserver for resizing on the fly and then let nginx cache it. In a VM with 4 cores from i7-920 it thumbnail 2-6 images per second. After first access images are taken from the cache.
