Speed problem

I agree, rsh as root is bad.  I wouldn't suggest that.  I'm talking about 
running "rsync --daemon", using /etc/rsyncd.conf to control the form of 
the access.  It's pretty good for reading, and mostly works for writing.
Oh, on our security - no ssh, but rsh is ok for root.  I'm also 
exaggerating a bit on the reason we don't have ssh.  I just can't convince 
the decision makers that it is important to have it and that rsh is 
leaving them buck naked to being 0wnz0r3d.  Oh, well, it makes it easy for 
me to get root in an emergency, and so far, we can trust everybody on our

This would be an option, but doing rsh with a root account is not
possible (couldn't get it to work, I haven't found any way to do it for 
and I really want to do it with the root account because I wanna have
the same file, directory and user permissions on the files) and also
not quite recommended... (.rhosts ??? Sheer horror ! ;-))
Maybe it is the encryption but I use ssh otherwise too and can get
on the same line results upto 12 MB/s (blowfish) and even 20 MB/s 
without any loss of speed. The funny thing is, it seems to happen
only after a short while. The first 5 minutes seem to be going good,
almost 18 MB/s (also arcfour which means, this is very similar) and then
it goes down. It never goes up again, even when a new file get 
but it starts at 18 MB/s when I start the complete rsync again.
