Recent change - crawling slow speed accessing NAS
Although I have been plagued long term by the same problem others have posted about (slow browsing of large NAS directories on Mac OS) my NAS was behaving fairly well for its most common uses - streaming music or videos, including 1080p content. Recently those activities began to slow and degrade (not sure if this was instant or gradual as I've not been using my NAS a lot recently). Now the device appears completely normal but it basically useless. No music or movies can be viewed, directories take for ever to populate on my Mac (both for those Macs on WiFi and others wired to the network, including different generations and OSs). Copying large movie files from the NAS to a wired Mac on the network does not appear to be possible. speedtest.net shows plenty of bandwidth when accessing internet (again WiFi and wired, 10-20 Mbps). A very rough guess seems like a problem with the networking function in the NAS. All disks and fans show healthy and no problems. Tried several Mac and NAS reboots and no improvement.
Where/how to I even being to troubleshoot this?
I can certainly provide much more information but here are some basics. Other than updating to RAIDiator 4.2.23, I have not made any changes to my Macs, network nor NAS.
-ReadyNAS NVX
-Enable jumbo frames - off (its never been on AFAIK)
-Performance tab: Disk write cache and disable full journaling are checked enable fast USB is unchecked
-Just tried update to RAIDiator 4.2.23 - no improvement
-Using AFP
-X-RAID2, 4 disks, all 4 are Seagate ST32000644NS
-OSX 10.7.5 and 10.6.8
Thanks in advance.

- Talked with Netgear support. Very helpful. I referred them to this thread for background. They suggested a full reinstall of the firmware. The only settings lost (back to factory defaults) were IP and FV admin login. This definitely made a performance improvement but it is still nowhere near as fast as it has been for the entire rest of its life.
I also testing accessing the NAS through a virtual Windows 7 machine on one of my Macs (one that is slow) the speeds there seemed better (although I was only able to test that through WiFi so I did not bother doing extensive testing).
I am leaning toward a Mac/AFP issue and perhaps with 4.2.23. - Netgear support suggested connecting the NAS directly to a PC or Mac by Ethernet and test speeds. Did that and things look great. Even better than before the problem that initiated this thread. My network here is a very simple/typical home network; cable modem, WiFi router and separate switch (just needed some more ports). Anyone have any idea how to continue to troubleshoot?
- What brand/model are the router and the switch? Also, what are the PC and the MAC connected to?
- Problem solved. Bad (physical) port on WiFI router (going bad technically speaking). I know, I know, check the simple things first. I'm not used to having to check for degradation of ports on a router/switch.
