What indicators does the "I/O total rate" include? #2609

You can notice that the I/O total rate is very high, but it is not due to network or disk access. Is it memory or something else? I don't see any other fields containing "rate" in the Choose column, so what else do these indicators include besides disk and memory? thanks |

I/O counters are tracking of I/O control activity on the system (see: IOCTL and FSCTL). These counters are updated when a related IRP is serviced on the system. Since an IOCTL can be arbitrarily defined for the system by any device - the counters can be updated by any number of operations on the system where a device is servicing some request. So providing all the possible things that the I/O counters are associated with is not possible. These counters are a generic measure of activity of the process/thread/job is transferring to and from the kernel. |
