Not able to get full throughput when using qos/limiters
I just upgraded our router to the XG-1537. I have tried using both altq shapers and limiters but cannot reach anywhere near full performance when using them. For example I tried to apply a 500Mbit limiter to our guest network but it only gets around 200Mbit. Same problem when using the traffic shaping wizard. According to the stats nothing is getting overloaded. I have verified the traffic is been put in the correct limiter bucket or queue. Is this performance normal, do I need to return the XG-1537 and look for something better?
If you haven't already try system > advanced > miscellaneous
and enable powerd and set it to maximum
@bobbenheim It was set to Hiadaptive. I just changed it to Maximum. I got around 150 which is in the same range I was getting before.
@jahinkle What results are you getting without qos?
Hi @jahinkle -
Got a couple questions for you:
- When using Limiters, what are you using for Scheduler and Queue Management Algorithm?
- Have you already tried increasing the default queue size(s), especially when using ALTQ based shaping? It looks like you have pretty fast connection so the defaults may be too small.
Hope this helps.
@bobbenheim 940 or so
@tman222 when using limiters I disabled all altq shapers, using tail drop for management algorithm, worst case weighed fare queue for schedulers.
When using shapers I was using hsfc. Default queue size from wizard.
