Hi PhilipD,
no I am not having any problems at all. I just wondered how it is possible for people to have really clean looking BQM graphs (Chrysalis for example) with pfsense, when mine always look awful!
As an aside this is from when I was with BT 2 years ago, and my pfsense rig was way OTT (Intel i3 8100, 16GB, Optane ssd, Intel i350-T2):
And this is with AAISP one year ago:
Hi
I think a lot also depends on the ISP and general congestion in your area, and it can vary, sometimes my chart is completely clean green and other times more yellow spikes.
What we are needing to look out for really is an increase in blue along with the green minimum latency going up as per Thinkbroadbands examples of congestion. Also I bet if you ping say the BBC constantly the latency never various even though Thinkbroadband shows some spikes during the same time.
When your line is under full load you are probably having buffer overflows so packets are getting dropped, hence the red. To test if this is the case run Thinkbroadbands speed test then look at the analysis and it will tell you your buffer bloat rating, I get As with pfSense and QoS enabled and much lower results with it disabled. It's not a free lunch as what the QoS will be doing is causing TCP traffic to slow down to leave a bit spare for things like UDP packets that can get lost completely, including pings.
Regards
Phil
