Dave has a point here about the possibility of stopping QoS during testing.=

Thoughts?

Well, actually, doing this this way, wou= ld get some GREAT data from the field that simply doesn't exist right n= ow...

/etc/init.d/qos stop
do the test (which I assume includes s= haperprobe and a bandwidth test)
/etc/init.d/qos start
do the bandwidth test

I've also been co= llecting data via usb sticks on these puppies. For slow connections (less t= han 2MB/sec) the writes to stick and the dump do not seem to permute the re= sults much.
