You might try this suggestion from the Shorewall TC HOWTO:
Note
For fast lines, the actually download speed may be well below
what you specify here. If you have this problem, then follow the
bandwidth with a ":" and a burst size. The default burst is
10kb, but on my 50mbit line, I specify 200kb. (50mbit:200kb).
