Well, our concern with the browser based tests was that - as of 4
years ago - your typical browser and pc could not drive the network to
saturation at speeds much greater than 20Mbit reliably. Neither could
netalyzer.

Thus, netperf-wrapper - now good to 40Gbit - was born.

So some work on determing the real cpu usage and network capability of
the client machine for these tests would be nice. I certainly do see
bloat on the comcast 110 and 200Mbit services almost as severe as the
lower end services using the netperf-wrapper tests.
