Hey Everyone,
I'm struggling to get FQ-Codel working correctly and could use some suggestions. I have been using
https://www.lullabot.com/articles/eliminating-robots-and-voip-glitches-with-active-queue-management
and
https://forum.opnsense.org/index.php?topic=7423.0
as a guide, but my numbers are not what I think they should be. Mostly on my download I seem to be loosing about 50 Mbps, but I'm not sure why. My connection is a 300/30 Mbps cable line. Here is what I have setup so far.
Pipes:
Downstream Pipe -
Bandwidth => 290 (300 Mbps minus about 3% for overhead)
Metric => Mbps
Mask => None, Codel Off, Pie Off
Advanced Options -
Scheduler Type => FlowQueue-Codel
FQ-Codel ECN Checked
All others default/blank
Upstream Pipe
Bandwidth => 29 (29 Mbps minus about 3% for overhead)
Metric => Mbps
Mask => None, Codel Off, Pie Off
Advanced Options -
Scheduler Type => FlowQueue-Codel
FQ-Codel ECN Checked
All others default/blank
Queues:
Upstream High Priority Queue (From lullabot link, for TCP ACK and DNS)
Weight 10
Pipe - Upstream Pipe
All Others Default
Upstream Regular Priority Queue
Weight 1
Pipe - Upstream Pipe
All Others Default
Downstream Regular Priority Queue
Weight 1
Pipe - Downstream Pipe
All Others Default
Rules
#1, Interface WAN, Source Any, Destination 10.0.0.0/24 (LAN Network), Direction Both, Queue Downstream Regular
#10, Interface WAN, Proto TCP ACK Only, Source 10.0.0.0/24 (LAN Network), Destination Any , Direction Both, Queue Upstream High Priority
#11, Interface WAN, Proto TCP, Source 10.0.0.0/24 (LAN Network), Destination Any, Destination Port 53, Direction Both, Queue Upstream High Priority
#20, Interface WAN, Source 10.0.0.0/24 (LAN Network), Destination Any, Direction Both, Queue Upstream Regular Priority
With these settings I get an A on bufferbloat and my upstream seems to be great, but I seem to loose about 50 mbps on my downstream.
Any thoughts? Suggestions?
Thanks
When you only have ONE queue, you can just leave it, or try weight 100
Seems to have fixed it now. Thanks!

What did you change? I'm having the same issue - speed should be around 300Mbit, hitting max 130Mbit when I activate the rules.
My setup:

First off, I'd disable ECN, just dropping the packets seems to work better.
Second, weighted queueing doesn't work with fq_codel, so you might as well just use one queue with weight 100 instead.
