when i applied janis example http://forum.mikrotik.com/t/burst-for-each-tcp-connection/10713/1
it may work if i download with just 1 connection , but if there is more than 1 connections , and they are small connections as what download accelerators do , it cant be possible to differentiate between download and browsing connection ,
so its not working in real life , with most ( 90% ) of network users ..
