Stealth_01 Posted December 28, 2018 Share Posted December 28, 2018 Hi all, Ive been running some ping plotter tests and ive found some interesting results. Ive got my QOS set to 70/70 with the anti-bufferbloat as always on. As you can see the results aren't very promising. I've pinged multiple ip's with near enough same results. Ive been running these tests throughout the day whilst other devices have been streaming content, surfing the web etc.. From what I understand, the QOS should prevent all local congestion from allowing my ping to spike. So why am I still getting this? Link to comment Share on other sites More sharing options...

Zennon Posted December 28, 2018 Share Posted December 28, 2018 Are your plots flat when your line is idle with nothing using bandwidth ? Link to comment Share on other sites More sharing options...

Administrators Netduma Fraser Posted December 28, 2018 Administrators Share Posted December 28, 2018 Can you change the trace interval to 2.5s and try again please Link to comment Share on other sites More sharing options...
Stealth_01 Posted December 28, 2018 Author Share Posted December 28, 2018 Graph from modem only no devices connected. Other than a tiny ping spike its pretty steady. Link to comment Share on other sites More sharing options...

Stealth_01 Posted December 28, 2018 Author Share Posted December 28, 2018 As per request fraser, but I cant understand why you want the 2.5 second intervals when the 1 second intervals are alot more accurate imo. With a game like BO4 and other first person twitch shooters it only takes a 1 to 2 seconds to die. So a short drastic ping spike like you see on my initial graph will make all the differance.

Administrators Netduma Fraser Posted December 28, 2018 Administrators Share Posted December 28, 2018 Zennon might be able to back me up on this but I believe there was some issue using 1 over 2.5 on PingPlotter? Link to comment Share on other sites More sharing options...

Yes sometimes anything lower than a 2.5 can show packet loss when there is non in reality. The difference is not massive from your idle line to when you are saturating it, you have around 5ms of jitter when it spikes while Idle that jitter is only moving to 10ms max when saturated, where if you had no congestion control in may be in the 40-50ms range or higher. I personally think this looks ok for a line that has a bit of jitter to start with. Are any of the devices that are using bandwidth in the traffic prioritisation? as this will make larger spikes as the packets are prioritised. If you want I could team viewer in and run some tests for you tomorrow but I think you have nothing to worry about.

No devices at all being prioritised other than the ps4. The 1sec intervals is not showing packet loss, only spikes. The graph is pretty much steady when im directly connected to the modem @ 1sec intervals, so evidently ping plotter seems to be working fine. id be glad if you could take a look, let me know if your free sometime tomorrow or in the near future Regards Link to comment Share on other sites More sharing options...
