I was thinking about what I said in a previous message about the control information added by rsync on the packets sent. I think this would be important only if we focus on the performance (number of bits of data sent / total number of bits sent). In this case, the focus is the transfer rate, for which the amount of control bits used would be irrelevant since I think we need to know how many bits per second we are getting, regardless of the utility have those bits. > And as we discussed in another thread some time ago, (especially) if > you're using wireless, benchmark throughput in *both* directions, > since the transmitter (or receiver) may be better on one machine than > on another. Interesting sidelight. Thanks for sharing. Kind regards, Daniel
