Any network experts out there?

Yes not great that.

I am no expert but I would first check that the router is both gigabit and wireless N, if not then the ready nas will be restricted to 100meg networks. now with network over head and all that 2megs is probably not a million miles out, typically 9 if you are lucky.

If the network is indeed gigabit etc then my next question would be how the drives are configured. I have no idea about the ready nas but how are they formatted? If fat 32 then this could be a limiting factor.

Another issue to consider is the transfer of that data is it going from the mac wirelessly then to the router?

Try opening terminal on the mac and typing this in:

sudo sysctl -w net.inet.tcp.delayed_ack=0

Enter your admin password.

you should get a confirm of ack 3->0

Now try a transfer.

Remember also that many small files will transfer a lot more slowely than one large file (say a zip file for instance)

This is very strange! Wired network should be very fast, sounds like something wrong with the drivers for the network adapters or the network adapters themselves. You could check with the manufactures' sites to see if you have the latest updates. Also, open the network settings, check for the Rx/Tx settings, bandwidth, etc.

As for wireless, it seems to me that you have non-N network. I have both G and N wireless networks at home, for G, the network speed is around 2 MB / s and for N the network speed is around 5 MB / sec between a Mac and a PC, despite whatever they say about the theoretical limits. I guess the slow speed of copying could be due to 2 different file system formats.

Personally, I am not very keen on the NAS solution. I would use a PC or a Mac with some large disks as server.

Hi,

I bought a ReadyNAS for use with my Sonos in anticipation for a Naim DAC. I got the NAS setup OK but the speeds are really slow, about 2 Megs a second so a album takes about 3mins to transfer. Will take a while to transfer my 2000 albums!

Setup on the network is the ReadyNAS, Netgear router, PS3 and the Sonos. The router and NAS have the standard settings. The only error I can find in the NAS log is quite a few TCP Retransmits. I get the same speeds using wireless or wired. Latest firmware for both. Accessing using my Macbook Pro

I am not really a network techie and find other forums on the topic confusing so any help really appreciated.

Thanks.

That is indeed a bit slow.

Using FTP on a Gigabit wired network I get speeds about 9 - 12 Mb/s. FTP has the advantage I can just fill up a transfer queue and I know it will finish correctly or can just be restarted to complete the rest if there was a hick-up.

Using SAMBA to a windows drive mapping, it gets up to 28 - 58 Mb/s but then there is no easy restart and I would have to check manually or with some tool to verify what has and what hasn't got across.

So for large transfers I generally use FTP and for 'small' transfers of several albums I use SAMBA connected to a Windows drive-mapping.

Doesn't the ReadyNAS use Netgear's own propriety file format on the drives ? - garyi's mention of Fat32 slowing things up (especially from a Mac) made me wonder whether this could be the same...?

Makes absolute sense. The HD reads / writes could be a limiting factor.

To verify, you could try copying files from 2 different machines and then from one of your machines to the NAS.

The mac could be a limiting factor as he does not mention PCs.

Try the terminal thing, it won't kill anything and worse case reboot the mac to return it to default.

As I say on slower networks 100meg and wireless (including N) then 9-10megs is about your lot for NAS, just the way it is.

For gigabit then you can expect to get up to around 19-30 depending on the files, if lots of small files then lots slower than large single files.

Just a thought, but how is your current library backed up? If you have it on a mobile hard drive then you can plug this straight into the NAS via USB and restore the files directly. I've never done this with my ReadyNAS but I gather it can be done.

Just reading your post again, I see you say you get the same speed wired and wireless. This is astonishing. We use a ReadyNAS Due and we have on a few occations, when ripping a DVD on a laptop, forgotten to turn off the wireless adaptor so it tries transfering the file wirelessly rather than via the wired network. The progress bar indicates many hours, whereas if you cancel it and turn off the wireless adaptor it takes maybe 15 mins (?) I can't remember the exact times, but suffice it to say the wired is hugely faster than the wireless.

Gary

ReadyNAS have a very good forum.

There are lots of posts re: transfer speed issues on them.

Hi,

Thanks for all the input. For some reason the mac was still using wireless even when connected with the cable. Turning off the wireless on the Macbook did the trick. Turned the wireless back on and it works via cable now too

A bit weird but glad it works

Thanks

That's exactly the problem I was descibing above - most of the time when you plug in a patch lead, the laptop connects via the wired network, but on occasions it remains connected wirelessly. I alway try to remember to disconnect the wireless adaptor.

On a mac just goto network in system preferences and drag ethernet to the top of the list, this tells the mac to connect via ethernet if choices are available.

To see how you are connected goto the network preferences which ever one is at the top is how the mac is currently connecting. If you have wireless going then plug ethernet in and ethernet is the preference this will become the connection, it should be seamless.

My guess is the OP has corrected the problem but not how he thinks. By default ethernet is always the preferred connection on a mac.
