OK, this goes to NFS. My assumptions just were proven wrong. We are talking
to a very slow off-machine destination...
@David: I think we got the culprit?
it could be. I would say that as a test we should try writing to local disk and
compare. Sometimes these high-end NFS servers are very fast.
But if it was me, I would have rsyslog write the files locally, and then when I
rotate them, move them to the NFS storage. Far fewer variables that can affect
performance that way.
It's actually impressive that he coudl do 250 logs/sec via NFS.
