I have slow speeds so should I use Reactive or Preemptive?

[Shane]

Hey,

 

I have slow speeds (Like 4MB slow  ) I have the option to get Virgin Fibre Optic but they're jitter and ping spikes is crazy whereas my slow BT connection is stable. I recently seen someone say that for speeds like mine Preemptive is the best algorithm. I currently have mine on Reactive. Why should I use Preemptive? What's the difference?

 

Thanks

How I tested when I had 6Mb as I tested when I moved to fibre is...

 

Run ping plotter while you run a speedtest from speedtest.net this will saturate your bandwidth up and down stream while switch from preemtive and reactive at 70% CC each way.

 

This will show you the better of the two at keeping pings low while there is traffic on you network.

 

For me it was reactive for both lines at around 2ms jitter when saturated.

I'll give that a blast after work tonight cheers Zennon

Preemtive is a Netduma exclusive algorithm and reactive uses sq_codel

 

Its very line dependent it seems on which works best.
