I/O Utilization

[aviwil]

Utilities like Process Explorer provide a %CPU display entry for each process . Process Explorer has an entry for I/O Read Bytes and I/O Write bytes - however I'm not really sure how to interperet this . Is there any utility providing a % utilization of I/O Bus ( or something like that ) display for each process ? I would like this beacuse sometimes there is not much CPU utilization , and it would appear that the I/O Bus is a bottleneck .
Thanks .

The Bottle neck for what?

Process Explorer is geared toward the Processes. If you Right click on a process, and choose Performance it would show you what the specific Process is doing.

If you think that you have a general I/O hardware problem you probably have to use an other application.

Thanks JackMDS . Maybe I didn't explain properly . The PC is going slow , ther is little %CPU utilization , so a utility which could show me % I/O bus utilization - in general and specifically per process ( if this is possible ) , would be a big help to me to understand what is happenning . Is there any such utility ? I am on Vista Home Premium , on a HP laptop , by the way .

This is free run it it might give you a clue about what is running slow.

Otherwise, post the Hardware spec. of your system in the General hardware Forum, and you probably would get a lot of responses.

You might find something that will tell you the amount of data each process is reading/writing (actually, I'm pretty sure taskmgr will give you some of that) but I doubt you'll find anything that will give you an accurate representation of %. Simply because there's too many variables when it comes to disks. With disks you'll almost never see them come close to the upper limits of the bus or disk itself during normal usage because of things like contention between processes, filesystem overhead, etc.

Thanks JackMDS and Nothinman - Crystal looks very interesting .
