If this were a car then you would be showing the speedometer and the odometer. It makes it very difficult for the GlassWire staff to answer your question. I'm looking at your screenshots, and there is nothing in them that shows any discrepancy.
You should show something that is reproducible so GlassWire staff (and even other users like me) can see there is a problem. You could, for example, show the GlassWire Graph for the same 60 second period. You could do this by displaying the
5 minute view and use the sliders on the bottom graph to reduce the view to one minute. But even if you do that there are a lot of issues as should be visible in my example:
- The graph styles are very different so the results only approximate each other
- Task Manager is rounding traffic flows so it shows no traffic during periods where it is very low.
- GlassWire autoscales so it is very difficult to get the graph scales to match.
What you should do instead is right-click on the Task Manager network view and select
View network details because this will show you accumulated bandwidth which you can compare with GlassWire's Usage view:
