Hello,
I have two Windows Server 2008, Server A and B. Both ones have exact
same hardware and same O/S version. However, server A is slower than
server B. How do I realize that? For example, if I have to unzip a zip
file of 1GB, in server A this task takes double time than in server B.
I can only think that there is some program in server A that makes it
slower.
However, if I run "resmon", it shows that server A is consuming 8% of
memory and server B 9%.
So, what could be making server A to be slow?
How could I compare what programs have server A and B?
Would be OK for both servers to list installed programs or to list
services? Would be there a way to list both things?

There can be a lot of reasons for this behaviour, from HW issues, to software problems, deadlocking issues, memory leak's....

in order to list services:

sc queryex

in order to query for installed software:

wmic product

or you can just export the registry key that holds that information.

But, to be honest, i think that another approach to your troubleshooting will be better. Start listing processes and compare them. You can do it from a commandline using: tasklist

That will list each process running in each server, save it on a text file and compare them. Look for matches and differences.

Enable counters, disk time, cpu and memory will be a good start point.

Enable a baseline with data coming from counters, is the server always bad performing or just some timeframe?

Good Luck!
