Ok, I tried this with HTB
the next time i recompile my kernel i'll include it and see if it is more effective in my scenario.
You could probably also get away with assigning 220kbit/s to your interactive class and 1kbit/s to the bulk class, but allowing it to borrow up to 220kbit/s, which would save you from trimming off 10%.
i allready tried that (not with HTB of course), but this resulted in the bulk class borrowing so much from the interactive class that it rendered the interactive class non interactive :)
