ReadyNAS Duo giving very low access speeds on local PC
My parents' ReadyNAS Duo is incredibly slow to access from their PC. I'd give a transfer figure but it's currently showing 0bps! Even displaying folders or right clicking on a file is very slow to respond. Both the PC and NAS are plugged into a gigabit router (the NAS is showing a 1Gbps connection while the PC seems to have a 100Mbps network card). I'm simply trying to copy some music files from the NAS to their PC, nothing too esoteric... The NAS looks healthy and I've rebooted it. I'm connecting remotely but I can't see that having any impact as all transfers are happening locally.
Can anyone suggest what the issue may be or what further diagnosis I should perform?
Thanks,
Geoff

- OK, some figures. I have the same files on my ReadyNAS Duo and it's plugged into the same type of router as my parents have. My PC has a 1Gbps link (the only obvious difference) and Windows is reporting 18.7MB/s whereas my parents setup is getting 26.3KB/s. That's quite some difference...
- Perhaps an incompatible switch?
Have you tried another switch or a direct-connection?
Have you tried a 1Gbit NIC in your parent's PC.
What version of RAIDiator are you running? - (some overlap with mdgm's questions)...
What firmware is running on the NAS?
What happens if you set the NAS to run at 100 mbps?
Do they have ReadyRemote or ReadyCloud installed on the PC? (if they do, they might try uninstalling it).
With fast ethernet, you should be seeing ~10 MB/sec - It's a broadband router rather than a switch and we both have the same broadband supplier and hence have the same switch (BT Homehub 5). I'd assumed it was running the latest version but it seems I neglected to update theirs when I last updated mine, we're now both running 4.1.14 (which made no difference). However, setting theirs to 100Mbps (full duplex) has now yielded a transfer rate of 3Mps (and rising, I assume because of Windows' averaging method) so I see that as a good result. Do you have any idea why running the NAS at 1Gbps and the PC at 100Mbps led to such a bad result? I'd have hoped the network could have coped with that...

Most likely the router does not support ethernet flow control. Maybe try NasTester (http://www.808.dk/?code-csharp-nas-performance), it gives pretty good speed measurements (better than windows).geojay wrote: It's a broadband router rather than a switch and we both have the same broadband supplier and hence have the same switch (BT Homehub 5).

Anyway, there might be some tweaks to the Windows TCP stack you can make. You could also get an inexpensive switch that supports flow control (or better still get a gigabit nic card for the PC).
