[Cerowrt-devel] speedtest.sh script available

[Aaron Wood]

Nice!  It gives me what I'd expect for my setup, although the TCP rate is
only 2/3 the line rate on DSL (upload is better at 80%).

..............................................................
 Download:  14.09 Mbps
  Latency: (in msec, 62 pings, 0.00% packet loss)
      Min: 30.157
    10pct: 30.691
   Median: 33.412
      Avg: 34.044
    90pct: 36.970
      Max: 48.250
..............................................................
   Upload:  0.87 Mbps
  Latency: (in msec, 57 pings, 8.06% packet loss)
      Min: 30.655
    10pct: 30.744
   Median: 36.658
      Avg: 36.379
    90pct: 41.414
      Max: 46.451

I'm running 21000/1100 as my rate-limiting settings in CeroWRT (3.10.32-12).

That packet loss is what kills my UDP ping streams.  It doesn't seem to
happen if I use the Free.fr box directly, and only shows when I use CeroWRT
as the bottle-neck.
