When I'm capping out on my download speed, my connection quality drops considerably.
This behaviour is usually expected when approaching the max download speed, but in past experiences it usually just bumps it up to about 100ms to servers in the UK. Recently, when downloading, even at about 200kbps of my 10mb line, my latency increases to well over 900ms which effectively kills any hope of using VOIP or streaming content.
I've looked at the connection settings, and the scheduling type is best effort.
When you are downloading even at 200KB/s you send very little back to acknowledge what you have received and mixing these acknowledges for your download and sending VOIP is likely what’s causing VOIP problems.
All of which would point to VM optimizing the upstream for high latency fast upload speeds then low latency slow speeds at the users ends and maybe the scheduler itself.
