Hogging the Ethernet in Windows

ethernetperformancewindows

The entire laptop is running slowly. It is new a few months ago, bit a Core i7 processor & 64gB RAM, both of which look ok on the task manager's performance tab. But Ethernet usage is spiking periodically. How can I discover what is causing this?

To me it looks like the ethernet is not really an issue. The graph and value show 568kilobits which isn't particularly large. Brief spikes in traffic are not really an issue and the fact that the graph has not readjusted suggests that the spike is not much larger than what is seen.

My main concern is this:

You have at least 1 CPU core pegged and giving a solid 25% CPU use and 0.78GHz is a common speed for CPUs to be stuck at during a thermal or power throttling event that has locked the system down.

Often this is cleared either by rebooting, fully removing power for a period or otherwise clearing the CPU temperature issue.

If nothing else there is ThrottleStop which can be used to bypass CPU throttling. I've seen a few indications that disabling BD PROCHOT should release your CPU throttle in a lot of cases but bear in mind that if your CPU (or chipset or GPU which all may contribute) is overheating then this could actually be a bad thing to do.

In the first instance I would be looking at the easy fixes of rebooting the system including chipset and thermal sensors by fully removing power.
