PNG File Benchmarks

All tests were performed on a Late 2011 MacBook Pro (2.4GHz Intel Core i7, 8GB RAM) using gtime v1.7, gpg v2.0.22, and crypto v1.1.0.

Use of compression with the -z 1, -z 7, and -z 9 gpg options did not lead to a significant change in file size for png files. crypto disables compression for png files (and all other binary files) by default in order to improve encryption performance.

The png file tests were performed on a directory that contained eight png files that ranged in size from 88kB to 7.3MB.

The results were:

The total CPU time for the GPG Default, crypto Default, and crypto --speed runs were 1.15, 0.51, and 0.48 sec, respectively.
