  Or it does not use all cores.

  is there any tool out there that monitors IO calls from one specific process? I get extremely annoyed when applications simply freeze without them doing any important cpu task.

    resource monitor in windows can do that

      It does not monitor latency caused by cpu doing fetches from ram (to the cache) though? Depending on the app, they can be a real killer.
