limiting speed with pcq and queue tree

alexspils · October 23, 2009, 3:58pm

anybody had success with limiting speeds about 50 mbps(pcq-rate=50m) using pcq+queue tree shaping ?

In my particular case, I have not tried with this bandwidth. But it should work correctly!!!.

i cant reach this speed with pcq.a set pcq rate to 55m and cant reach 25 mbps.mikrotik answered that this is pcq bug and they can`t do anything with this.

simply increase ‘Limit’ and ‘Limit Total’ parameters of pcq. higher speeds need longer queues

chupaka:
can you tell me values for limiting 72 user at speed 55 mbps.

I think, it depends on packet rate. I simply checked with default settings (got ~25-30 Mbps) and then with Limit=500, Total-Limit=20000 - and saw honest 50 Mbps of traffic

tryed with these values and cant get these speeds.With b-test from pc to router i can reach 100 mbps, from router to world - 1gbps, but i cant reach 50 mbps using pcq.chupaka, what hardware do you use?

I’m using x86 (something like Core2Duo 2333 MHz), ROS v4.1
