Just try it... Generating large file with tc classes and filters and
then loading it with "tc -b" takes less then 1s on most system.

If you're worried about active connections - don't be. Shaping restart
won't break them.

I use this solution on routers with thousands of filters and classess
and full restart intervals as low 1 min. It works well.

Whatever you do, change/add/delete you can always pack commands in one
file and load them with "tc -b". Again, it's faster.
