Extremely slow transfer speeds over ethernet
I have had my ReadyNAS for a few years now and have always experienced slow network speeds. I have always just assumed that the ReadyNAS was just slow, however I have been researching recently an...
Sorry I thought I already had that in my title!
Yes it is a Duo V1 running 4.1.13
I am doing this because the system will not accept firmware upgrades or shutdown without a command through terminal so obviously something is messed up!
I get that rsync is CPU bound, but I am running the command from the desktop PC with the NAS share mounted via NFS so this shouldn't use the NAS CPU at all?
I am currently getting about 4MB/s, this seems pretty slow considering it should not be involving the NAS CPU.
When you say transfer over NFS, do you mean using a cp command? The problem with that is not ability to resume a failed transfer.
I do not have jumbo frames enabled and the max MTU my router seems to support is 1500. I also don't know how to test if my Linux PC can support jumbo frames.
I have journalling enabled because I don't have a UPS and we have been having a few power cuts recently.

Often turning them on will cause the speeds to drop (esp if your router or PC doesn't support support them).

Have you checked for a full OS partition (e.g., df . -h and df . -i from terminal)?
