I am hoping to find a way to do more performance monitoring--specifically, I hope that monitoring disk activity on a per-process basis will help me decide which programs are causing the most trouble (aside from the AV). I'd rather avoid a shotgun approach.

For windows XP, is there a process monitor that can give me a solid idea of which processes are slowing me down by causing the most page faults, etc? Thanks!

Perhaps enabling the I/O reads and writes in the task manager (ctrl+shift+esc). When looking at the processes in task manager select View then Select Columns. Look for the I/O read optiona nd I/O write option and click them.

This is what I get:

  • Thanks! This is just what I needed. I ended up using Page Faults and PF Delta, for the most part.

  • Network communication is IO as well. With heavy usage of internet this makes the numbers quite uncertain.

  • @TomášZato this is true, but if a process is heavily spamming a disk drive, you'll more than likely be able to detect it using this method.

While I prefer the accepted answer, there is another way with the existing task manager.

  • Task manager > Performance (tab) > Resource Monitor (button) > Disk (tab)

  • This does get the "True" read/write IO to the disk drives. If have a lot of network or other IO traffic, the accepted answer may be masked by those other operations. This is a better option in this case.

I like the freeware Process Explorer. It provides a bit more detail than the Windows Task Manager, including per-process I/O graphs. Great for immediately spotting processes doing a lot of disk I/O.
