Question: In a nutshell, the problem looks like this picture:
In short, gigantic latency, very slow read speed (I assume that is caused by the same thing). After a very very painful few minutes, everything seems to go back to normal.
What the heck is going on that can cause that?
Note: Note the fact that 100% activity happens at a wide range of speeds.
Answer: I had the same issue.I resolved it by changing the power plan from ‘Balanced’ to ‘High performance’.Instant results.
