Encryption speed test

A problem with PoreXpert versions up to 1.8 was that the encryption necessary to protect the software slowed it down.  Using newly purchased software we have been working to improve the speed of the most commonly used operations, and have successfully applied it so they now run comparably as fast for our users as for ourselves.  The graph compares the speed of calculation for a (small) 12x12x12 unit cell, with about 4300 void features – fitting for Vertically Banded and Small Centre Zone structure types (short range size auto-correlations), absolute permeability to water at 20C, and ionic tortuosity.
