This is a screenshot, of me, over a vpn...

http= ://www.bufferbloat.net/attachments/download/33/routertest.png

mo= nitoring 5 clients' cpu and memory usage,
using pdsh and X to the routers in the lab,
while trying to understand w= hy performance peaked at 130Mbits and latencies had hit 100s of ms on conne= ctions capable of gigabytes.

(I had had several other problems on th= e way, which I'd quickly resolved)

Doing updates in the field is a = single command.
