Oops.....forgot to mention, this was on a Linux machine, I noticed yours was Solaris.

We had very similar issues to those that you mentioned and used the following nfs mount options. Performance picked up immediately
I think it was the noac that was killing it.

Subject: rman/NFS over internet, performance
I am trying to backup through an NFS mount to a disk located in a different datacenter between some solaris boxes. This works, but I am not satisfied with speed/performance. Using ftp, i can transfer data at more than 30mbit/s, while NFS peaks at only 16Mbit/s
I already use compressed backupsets. There doesn't seem to be a whole
lot to tune in nfs client settings as oracle requires tcp, vers=3 and
I tried to use more (and less) parallel channels but that didn't help much either.
Any more ideas?
