Test setup

The WMU-6000FS is tested both in wired and wireless mode. In wired mode it is connected to a gigabit switch and tests are run on a Gigabyte board with NVIDIA gigabit NIC connected to the switch as I don't expect there to be a bottleneck there.
In wireless mode I have to use a HP 8510W laptop with Intel Wifi card in ad-hoc mode as I only have an 11 Mb access point at home.
Unfortunately I broke my only decent performing 2.5" IDE disk half way during the tests, thus I use USB storage instead.

Performance

To verify the USB stick not becoming the bottleneck I tested it on my desktop first. Clearly it will not be the bottleneck.


When connected to the WMU-6000FS and accessed via a wire, performance isn't too impressive. 3 MB/s read and 2 MB/s write is about as good as it gets.


Wireless performance is worse, strangely enough write speeds take less of a hit than read speeds.


Additionally I tested the performance when acting as just an access point/bridge, I shared a folder on the desktop and tested performance from the laptop. Performance is slightly higher than when using the USB stick. My guess is that it simply lacks processing power to handle wireless and USB at once, and even doing either alone at high speed. This is no surprise considering it's an extremely low power device with no cooling at all.


Finally I tested FTP performance both wired and wireless. I did this by using the command line FTP client in Windows and uploading a 700MB file. When that finished I downloaded it again. Performance is about the same as the ATTO indication.
