Windows Performance Analysis help

[Guest KeithK]

I am realatively new to using perfmon and have been tasked with determining

the cause and solution to a problem with the time it takes to perform a

scheduled task that copies data from one server to another. The time to copy

(using XCopy) has nearly doubled overnight.

 

My plan is the following:

 

1) 15 min prior to the copy time, begin running perfmon on the following

counters:

Processor : % Processor Time

Memory : Pages/sec

Paging File : % Usage

Physical Disk : % Disk Time

Network Interface: Bytes Total/sec

2) 15 min past copy time stop running perfmon.

3) Import into PAL (Performance Analysis of Logs) for review and to try to

determine cause/bottleneck of the copy process in order to make a

recommendation.

 

I would appreciate any additional suggestions on how I should go about this,

any counters I should add, what I should I be focusing on in my analysis, or

any good artciles/books on the subject etc...

 

Thanks in advance!

Hello,

 

depending the number and size of files to copy, robocopy may behave better.

you will find it in the 2003 resrouce kit:

Robocopy can copy only missing or changed files to save time if possible

 

Check also for :

-networks error (on the switch and server)

-Be sure they are in gigabit or at least 100M/full duplex on both side

(servers and switch port)

 

Shutting down the antivirus client would help too.
