New ReadyNAS Duo user with slow Read/Write
Hi all, 1st time post. I'm seting-up my ReadyNAS Duo [X-RAID] and I'm having some performance issues. I've spent days going through the various performance troubleshooting posts but I'm getting no...
Wirelessly, your speed is good. Wired, it's weird. The fact that you're connected at 100 Mbps, you should see (wired) read/writes in the 10 MB/s range. Of course, you're getting 36 MB/s write (impossible on 100 Mbps network***) and 4 MB/s reads (too slow). I've written up a document that provides rough performance expectations: http://home.bott.ca/webserver/?p=363
*** Another possible reason for this is that your computer's NIC is actually a gigabit connection, and when you direct-connect, you're getting max. performance, as both NIC and NAS are gigabit. When connected to the router, the performance drops to 100 mbps. Can you provide details of your wired NIC?
The network errors may be attributed to the MTU being set to 1492. You can try setting it back to 1500 to see if it clears up the errors.
You didn't mention what OS you're using, however, I'll assume Windows 7. There are some known-issues with wireless performance in Windows Vista/7 and the ReadyNAS sparc-based units (NV+, Duo). I've written up a how-to on how to fix it: http://home.bott.ca/webserver/?p=226
Also, are you going to primarily be using wireless to connect, or will you be using both wired and wireless connections?
FWIW, I've always found IOMeter to be flaky. The best test is to drag & drop a big file (like a movie .avi file of 1 GB) and time how long it takes to copy to and from the NAS. There's a free program called TeraCopy that will give you a pretty good idea of real-world performance:
