I'm hoping someone has some idea of how to help here as I feel like I've tried everything.
I have a ReadyNAS NV+ V2 which works perfectly.
On my Dell Studio 540s desktop I get 30MBs reading from the ReadyNAS. For me this is a problem as I frequently copy large files from it to USB3 disks. I have tried:
Replacing all network cable (Cat6) New switch New Gigabit Intel CT network card Latest 5.3.8 firmware on Readynas
Whatever I try I cannot get this 30MBs number up any higher? I have a friend with the same unit and he gets 75MBs and he has an older desktop with worse components!
I'm really hoping that there is some magic setting somewhere that I have missed to speed this up?!
Hope someone can help
I know someone will ask so I tried copying from the ReadyNAS again using a brand new Toshiba laptop. This showed a mild improvement of 40MBs read but nowhere near what it should be capable of?
I couldn't see an option for Jumbo Frames on the NV+ V2, I don't think its available?
It's not - Sorry I wasn't more clear. I meant in the switch and the PC. Though that would affect write speeds to the NAS more than reading.
Are you using the default settings for the CT card? Also, how full is the NAS volume? Try opening a windows command box on the PC or laptop and try pinging the NAS with
ping NASIP -l 1472 -f
You should get a normal reply. If you get "Packet needs to be fragmented by DF set" then try to find the biggest number (after the -l) that gets a normal reply.

I am copying single files around 20-30GBs in size so no I'm not copying large numbers of small files.
ok. groups of small files are slower on the NAS side. But that isn't a factor here. Transferring a very large file could slow things down on the PC side - particularly if the disk is full enough that it gets fragmented. You might try a 1-2 GB file, just to compare. It would be also useful to know the write speeds.
BTW, NasTester is a simple tool which will time transfers for you - there's a (green) download link here; http://www.808.dk/?code-csharp-nas-performance You map a drive letter to a NAS share, and then enter that drive letter in the test tool.
No problem, the switch is non-configurable so no options to enable or disable jumbo frames there. I also made sure that it was disabled on the intel CT card. I have also tried lots of driver variations on the CT card all to no avail. I am using the default settings on the card and the NAS is about 70% full.
Here are the results of the ping:

I also tried copying a 2GB file but still got the 30MBs transfer rate from the Dell PC.
I hooked up an old HP desktop I had lying around today and was getting a transfer speed of 90MBs from the NAS unit. I think the NAS unit is perfectly fine so the problem lies in the DELL PC somewhere. I can understand if you don't want to help anymore as its more about the PC than the NAS now but any advice you have would be greatly appreciated as this is driving me insane. I need to backup 10s of TBs of data and the 30MBs rate will take weeks. I guess it does the involve the NAS in some way as I can copy from any other desktop PC or laptop at over 110MBs. I just can't see why the Dell PC would talk to the Readynas differently than any other computer?
I also have a NV+ v2 and Dell PC, it's a few years old with a 2.8GHz Pentium D CPU and Broadcom networking chipset. Funny enough (or not so funny really), I only get ~30MB/s. I notice in task manager that the CPU load is very high when I copy 1GB file from the NV+ to a local PC drive, but network utilisation is <25% (which seems correct given 30MB/s).
Could it be your PC is not up to supporting data any faster than this? What load are you seeing in task manager?
Thanks for all your help guys. I bit the bullet and did an entire rebuild of the PC and.... it completely solved the issue and I now get around 87-93MBs read and 36-37 write speeds. I have no idea what was wrong previously but a full reinstall of Windows 7 x64 pro has done the trick!
What is the PC spec, as this is a nice (impressive) jump in throughput. I have also recently reinstalled Win7 32-bit, so just checking really (convinced my PC platform is basically not up to higher LAN throughput. Hmm, it could also be the switch, the router, well any piece of kit between PC and the NV+. I'd still quite like to see your task manager workload if you don't mind.
No problem, I'm using an old PC actually I bought off ebay, its a Dell Studio 540s. Not overly powerful and I couldn't get these speeds using the Realtek card that was builtin. I bought a PCIE Intel CT gigabit card from amazon that did the trick. What is your PC spec? I also have an even older HP desktop that manages 80MBs read and 36-37MBs write.
A Dell GX620 with a Pentium D 2.8GHz. It is probably 8 years old (or more) - I bought it from my company a few years back when they upgraded a bunch of machines. I might even have a spare PCIe slot to stick in an alternate adapter, but I am considering a whole new PC soon anyway.
