I have an ADSLMax Premium connection with sync at 8Mbps down 800Kbps up (speedtests report 5.5Mbs down 500Kbps up). I have a variable latency, which is noticeable when using VPN and/or Lync/Skype. I do run servers, but they don't get heavy usage (CPU is typically less than 1% utilized, and peaks at about 5%), and I have a Vigor 2860n+ router, which also reports low cpu utilization.
The latency gets noticeably worse in the evenings, so I'm suspecting that it is due to congestion - this is the Netherend exchange, which is quite small.
My question is are the attached graphs what would be expected for ADSLMax Premium, or is there evidence of congestion?
23-01-2016 I was away that day, so the peak traffic wasn't me, and the server didn't log any significant activity.
