6 is doable but it's the limit. For intervals shorter than 4h another
method would have to be used.

The problem, in our case, is not the download, it's the scavenging of
an enormous tree to determine what has to be transfered. This is very
heavy because it's almost only disk seeks.
Yes, this part of the sync process is time consuming and is what will
eventually limit the frequency of pushes.
I would like to see trials on a mirror by mirror basis before the
pushing frequencies are increased arbitrarily. I'm sure we can take 3 a
day and even 4. But more than that will probably jam things.
