Revision 4. </p> <p>This is a pure Python implementation of the <a href="">rsync algorithm</a>. On my desktop (3.0GHz dual core, 7200RPM), best case throughput for target file hash generation and delta generation is around 2.9MB/s. Absolute worst case scenario (no blocks in common) throughput for delta generation is 200KB/s to 300KB/s on the same system.</p> <p>Tested in Python 2.5, 2.6, and 3.1. In 2.7, io.BufferedReader should yield the best throughput. On all other versions use</p>
