RE: File Copies

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi,

Such performance issue is really hard to verify. For your issue, I have
following thoughts:

1. Check if the problem happens to other computer (different hardware)

2. When you perform first copy & second time, try to monitor the disk
performance to see if there are any differences.

Thanks. Hope this helps.

Can anyone explain why repeatedly copying a file from one drive to
another
within the same server would take varying amounts of time?

I am trying to benchmark performance of our servers versus the servers
at
our disaster recovery site. One simple test is copying a 1.5gb file from
one
drive to another.
I won't bore you with the RAID configs of each as I have alreadly
eliminated
that as the issue.

Essentially what happens is the first time you copy the file from say C:
to
D: it takes 30secs. I then shift+delete the file from D: and copy it
again.
This time it takes upto 2mins?!
I have also noticed that copy & paste takes longer than cut & paste. Even
though the two disks are entirely seperate (physical & array)

The servers I have tested on are running a freshly installed OS (I've
tried
2000 and 2003) and are running no other apps or services.

Any ideas?
