24.1 Legacy Series / Re: fq_codel console flood
« on: March 02, 2024, 12:25:41 am »
I think I may have found the cause to this, and that being setting the FQ-CoDel limit on the pipe too low, which, from the looks of it, the message it's spamming is (possibly) the number of packets it's unable to process because the queue is full.
Reading this document (posted elsewhere on the forum) https://datatracker.ietf.org/doc/html/rfc8290 showed me a number of the common recommendations are just, well, wrong.
FQ-CoDel quantum should be set at your WAN MTU (in my case, 1514 bytes)
FQ-CoDel limit doesn't really need messed with, this setting defines the maximum number of packets that CAN be queued. The default is 10240. Most recommendations are to drop this value significantly, thus, causing the console flood messages. For me, on my download pipe, I left this at the default of 10240. For my upload pipe (with a max speed of 40Mbps) I halved it to 5120. No real reason to, but my uploads will never saturate it.
Since changing these things, I have zero issues. I can post my complete config if anyone's interested.
