It's pretty hard for the ONT to be adding additional latency. If your link speed is what it should be, then the ONT should just be churning that data as fast as it can - it's mostly dedicated logic in there, so not what you'd think of as a conventional program that can slow down.
So I guess the question is, how bad is the latency when you connect to where?
I only learn by making mistakes and owning up to them - boy do I learn a lot!
