Yes, definitely. There are also other problems with scp/sftp protocols
which lower their performance on fast networks. These are being remedied
with the HPN patch (
http://www.psc.edu/networking/projects/hpn-ssh/) but
upstream still refuses to accept the patch and we don't want to diverge
from it so much. There is also a question if this patch couldn't cause
incompatibility with unpatched OpenSSH clients/servers in some
circumstances.
So I'd say, keep the rsh for now. Or even better possibility would be to
move it to Extras as Extras are NOT a second class citizen and RHEL can
still include it.

No matter how far down the wrong road you've gone, turn back.
Turkish proverb
You're truly right. This idea about high-performance systems doesn't
strike me. I'm going to look forward to this idea when upstream of
OpenSSH accepts HPN patch (or other improvement for this problem).
