NFS Slow - Rsync Fast?

I just got a 314 and am working on copying over ~3.5TB of data from my Ultra 4. Following the instructions found here I setup NFS on my two shares on the 314, created NFS backup jobs on the Ultra 4 and hit go. For whatever reason it was averaging about 4MB/s I did a few tests and I could read and write to both NAS boxes over an AFP share at upwards of 20MB/s over wifi. Out of curiosity I switched the backup jobs on the Ultra 4 to RSync instead of NFS and am now averaging 50MB/s

I'm happy to be copying data at a reasonable rate now but just thought I'd post this bit of experience since all the other posts I've found say to use NFS for the initial backup.

NFS isn't as quick with the 314 as it was with older devices. So as you have found Rsync is a good way to go.

Ah good to know, hopefully others looking to do a NAS upgrade will find this as well. I was really wondering if I messed something up with such slow transfer rates.

I think it could be to do with CoW. It's certainly got something to do with BTRFS.
