burst 19k will limit you unless your HZ=1000
Our HZ is 512.
I don't know if it makes any difference, but I would have chosen 500 so
that it was 2ms. The default now is 250 and with 19k burst that fits the
speed you get really well - with 512 it would be around 70meg. I would
get rid of the 2 burst settings you use.
Not sure can you show output of tc -s -d class ls dev eth0 while it's
running at 2x speed.

84198 bps - tc means bytes/sec by this, so it's < 1mbit. Htb uses really
long (100 sec) average for its rate so it probably is giving 1mbit.
