Are you sure bout that ? I'm throwing a lot of data through my machines
with ssh (also more than 15 - 20 MB/s) and it never got such a strange
problem that network speed starts high and ends up in a terrible slow
mess.

Hm, but to create those big files I never had those effects. It was
all the way straight. It's just a problem during rsync to another
machine ?

You don't mean that, don't you ? I mean this process should run
autmatically by night sometime...
And to say it clear again: it's just the network that slows down
not the whole machine and it does it only with rsync. Tomorrow
I'll try to test it with standard rsh, maybe it's the connection
between ssh and rsync that doesn't work good.
Anyway, thanx for all your answers. At least I'm a small step
further...
Mermgfurt,
Udo
