Anti-Flood Lag Spiking


Recommended Posts

Posted

Hello guys at Netduma, i was noticing when my sister's watch you-tube and Netflix that i would get lag spiking while playing. Is there a way a can get rid of these lag spikes???

 

 

Internet Speed: 15 down 1 upload

 

Congestion Control Setting: 70/70

 

Algorithm: Preemptive

Perhaps you could try setting it to 60/70 (where the download is at 60). Maybe that will be more affective :)

Do you have any devices that aren't connected to the R1 but to the modem itself? As this will cause issues like this as not all devices can benefit from the anti flood

Hi Avery, glad to see you have your netduma. Ok few things to try here. Firstly your upload is pretty low so lets do the maths to figure out what you need.

 

So you've set anti-flood in the upload direction to 70%. Assume a game needs 0.3mbits (that is quite high but I'm being extra liberal so you don't have any issues). 

 

By setting 70% anti-flood your upload is 0.7mbits availble. So you need 0.3 out of 0.7 mbits for your xbox at least. So that is (0.3/0.7) * 100 = 42%. So I suggest you do the following:

 

Set anti-flood to 70% each way. Then set the xbox to have 50% (just take a bit more) in the device prioritisation. Finally if you're still having spikes either reduce the download anti-flood or try the reactive algorithm.  

 

Incidentally I'm working on anti-spike feature as we speak. The results are looking very promising so far, need to do real world testing. But in the lab achieving 100% goodput with less than 1ms spiking in 2 min simulation :D

UPDATE: I still get the occasional spike but its usually not too bad. I cant wait for the next update so i can throttle per device.
