...rsync checksum. Given that we want to lower the standard deviation, this result implies that the block mask size should be selected to be as low as possible. 5. Earlier, I mentioned that the value that probably impacts the performance of the compression algorithm the most is going to be (Xavg - Xstddev). If we look at that value as a function of BlockMaskSize, we find something quite interesting - there is *almost* no dependency on Block Mask Size! The effects of the increase in standard deviation pretty much wipe out any advantage of the increased average. For example, for the RSync checksum,...
