I suppose there is a definition of file access for which that might
still be true. I use rsync every night to mirror the rfc and i-d
archives on my laptop. Works great. It is not 1995 any more and nobody
sensible mounts a remote directory for one at a time retrieval of
small files over a WAN.

>2. traffic volume is not an indicator of importance.

At some point of course it is. We're talking about 1/5000th of the
traffic here, with strong hints that a lot of that trickle could
easily switch to other paths.

R's,
