After watching Tom’s ‘How To Fix Bufferbloat in pfSense For Better Network Performance,’ I decided to see what my score was.
After running the buffer bloat test, I was getting an Grade A in bufferbloat but explained that ‘Your latency increased slightly under load’ for low latency gaming.
Since I love to game, I decided to watch the vid and try configuring my own limiter on pfSense.
I have a 1.2Gbps internet plan from Xfinity, however, fast.com states I get between 1.5-1.9Gbps down and about 39-42Mbps up.
When I run speedtest.net, I see about 951Mbps down and 36Mbps up.
I added 1450Mbps as my WANDown limiter, queue length of 3000. WANUp was set to 35Mbps with a queue of 1000.
After applying, bufferbloat test results is still A ‘Your latency increased slightly under load.’
I watched that video too, and I have a feeling you configured something incorrectly on the upload side. If you put in a limit of 35, why are you still hitting 40? I don’t think that should be the case.
Plus for what its worth, I scored an A as well. My upload active was +5ms which is on the border of A+ so I left it. I didn’t want to try and tackle this considering I have redundant WAN connections on two different providers. Too many moving parts.
If your DL didnt actually reach the advertised rate and you only got about 950 or so, if after doing multiple speedtests it averages out to around that, I would use 95% of that and put that in and not use the Comcast advertised DL speed. Cable is a fickled beast and is based upon how many users are on since its a shared pipe per see. So you really never know what you will get. Yes, you may lose some speed if you are really looking to get that A+ but the main thing is the latency. Also don’t try to do a speedtest over wifi. Too many variables there as well between dropped packets and retries.
I’ve applied some shaping on my vlans, I get a A+
Though I don’t game, before traffic shaping browsing on the internet wasn’t as good, after some sites were a bit more snappy!
I believe that we have very similar connections. Xfinity says 1200 but a gigabit network or cable modem typically gives me roughly 900/40. I set the limiters at 850/35 to get an A+.
