"I/O Other Bytes" by the system process is too high

Question

_{Tuesday, December 17, 2013 12:56 PM}

Hello everyone

the description of the performance counter "I/O Other Bytes" is "The number of bytes transferred in input/output operations generated by a process that are neither reads nor writes, including file, network, and device I/Os. An example of this type of operation would be a control function. I/O Other Bytes directed to CONSOLE (console input object) handles are not counted."

what I simply want to know how to identify this transferred data source and destination?

Thank you

Hi,

Please use Process Explorer tool to view more detailed information about system process. Go to "View" -> "Select Columns" then select the tab "Process I/O" and select "Other Bytes". Process Explorer shows you information about which handles and DLLs processes have opened or loaded.

In the meantime, please refer to the links below to see if they help:
