Poor performance ReadyNas Duo
Hi All, Many posts about this subject but I'm stucked. I saw the bad performance of my duo in the network. 1GB network,CAT6 cables, D-Link router. Write speed only 5,5 MB/s Read speed 10 MB/...
Well, the one-line answer is that if jumbo frames don't increase performance then you should leave them off.

I unchecked it and then the speed is mucht higher.
Strange thing is that my router supports jumbo frames (9000), it's a d-link DGS-1008D.
Also when I had thje direct connection the speed was low... might be my NIC?
Has anyone noticed this behaviour too?
The only reason jumbo frames improve performance is that sending fewer packets usually reduces the CPU overhead on the PCs. However, many newer NIC cards offload a lot of the packet processing from the PC to the NIC hardware anyway, so they often don't help much. There are likely some settings in the NIC that you could tweak; though if you are getting good performance w/o jumbo frames I suggest you just leave them off.
