As I have suggested in a previous message, it is trivial to implement adaptive indexing: there is no need to hardwire a specific indexing scheme. Furthermore, I suspect that the optimal size of subkeys may well depend on the filesystem. My experiments seem to indicate that subkeys of length 2 achieve an excellent compromise between discriminatory power and disk footprint on ext2. Btw, if, as you indicate above, you do believe that a 1 level indexing should use [0:2], then it doesn't make much sense to me to also suggest that a 2 level indexing should use [0:1] as primary subkey :-) Cheers, -- Dr. Denys Duchier - IRI & LIFL - CNRS, Lille, France AIM: duchierdenys - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
