This doesn't seem to be the worst point. I mean: the machine is not
going down under pressure or something like that. You can really
work with it. Only the speed is going down.

I tried this and it got slightly better, but the higher I set
the blocksize the longer I have to wait before it starts. And I can
only lengthen the time until speed begins to drop again. Maybe after
20 or 30 minutes I ran into the same problem.

Can you elaborate on that ? What's the problem ? Besides of this
problem rsync would be the perfect tool to move heavy data throughout
the machines...
