What metrics does saturating memory bandwidth manifest as? ...iowait? 100% system CPU? How does one isolate memory as the bottleneck specifically?

- zozbot234 9mo agoIn process monitoring you just see 100% "cpu" use with the processor cores running in their low-medium frequency range and no real thermal issues (fans aren't spinning up). You can use perf indicators to specifically look at whether memory bandwidth is the issue.
