Well, let's perfom a little calculation :)
"tc -s class ls dev eth0" :
> class cbq 10:200 parent 10:1 leaf 8026: rate 16Kbit (bounded,isolated) prio 5
> Sent 4049872 bytes 3846 pkts (dropped 0, overlimits 10286)
> borrowed 0 overactions 1364 avgidle 309677 undertime 0
after 4 second :
> class cbq 10:200 parent 10:1 leaf 8026: rate 16Kbit (bounded,isolated) prio 5
> Sent 4049926 bytes 3847 pkts (dropped 0, overlimits 10286)
> rate 13bps
> borrowed 0 overactions 1364 avgidle 309677 undertime 0
4049926(bytes)-4049872(bytes)T(bytes)
54(bytes)/4(second)\x13.5 BYTES PER SECOND!
It is easy to come to this conclusion when looking at MRTG graps.
