The total number of pool files with hash collisions. Since the hash is not computed over the entire file contents, it's common to get files with the same hash. > max chain The biggest set of pool files with the same hash. This is a potential performance bottleneck if the number gets too large, since a incoming file needs to be matched against every pool file in the chain. That means each file is O(n), and n files from a full backup all with the same hash takes O(n^2) comparisons. So it's a problem when this number gets too big. > max links The maximum number of hardlinks on any pool file. The minimum is 2 (anything with 1 is deleted since it is no longer used). This means that across all your backups you have one file that appears 11424 times.
