Hi

we usually see close to wire-speed with rsync or other tools...

Hmm, Isn't this rsync running locally?

What I would try:

On one host (usually the receiver), start the rsync daemon with an
appropriate small rsyncd.conf file and then from the other end try
pushing into it, e.g.

rsyncd.conf:

[test]
path = /path/to/lustre/storage
uid = user
gid = group
list = yes
hosts allow = *
pid file = /run/rsync.pid
read only = no

and on the sender:

rsync -avx --progress --stats /path/to/local/dir rsync://targetmachine/test/

What does this result in?

Cheers

Carsten
