ReadyNAS NV+ Seems really slow
I just bought a ReadyNAS NV+ 2x750 and am trying to transfer all of my data from a raid array to it so I can retire my old server. First I tried to use EMC to get all the files over to the NAS, but...

So, I've swapped out all the Seagate drives (so the Seagate firmware bug is now eliminated as a possiblity) with these new Hitachis. Of course, I can't EXPAND the X-RAID, so I've been copying all 4TB-ish using rsync. The BEST speeds I've seen in the last WEEKish of copying have been around 1MB/s. This is TOTALLY UNACCEPTABLE!!
Something is just plain wrong here, and has been so since the get-go with my NV+. The network, and particularly the NV+, is quiescent aside from this rsync process. I can get significantly faster throughput from a Linux box which is routed through even more switches than the NV+ (but includes going through the ONE switch between the NV+ and the target Mac).
1.15MB/s from NV+ to Mac is the BEST I can get, and only on LARGE files (small files drop to a few KB/s and each file takes a long time!)
16.71MB/s I just got from Linux box to Mac with a 756MB file.
Note: just for grins I rsynced a bunch of small files from Linuxbox to Mac. The reported speeds are also low, but the speed they run through (i.e. file after file after file) is EXTREME compared to NV+ to Mac doing the same rsync copy. Just a guess, but I'd say I could copy my whole 4TB from Linuxbox to Mac in a day. I think it was about a WEEK ago I started the rsync from NV+ to Mac and it's still plodding along, but I need to reboot the Mac soon just for general Mac maintenance!! :-/
