Wayne, when the Rsync daemon accesses the data (randomly or not), does it read its chunk at a position of n x <chunk_size> (n integer) from the beginning of the file ?
Are all the Rsync daemon chunks 256K chunks, or does it also produces 16K chunks as you seem to say above ? Which one is mainly used ?
Sorry to bother you but I did not understand exactly what you meant in your quotation above :-/
I'm still thinking about / working on performance :-)
Thank you very much for you support !
