terminal server 2003 perfmon pages/sec

[zerbie45@gmail.com]

hello guys,

I have a battery of terminal server used with office and some
financial applications. I noticed with perfmon that pages/sec usage is
always extremely high, costantly on top of the graph.

how can I find out which process is causing this high usage of ram ?
task manager does not show any possible culprits.

thanks in advance!

How have you determined that they are high? Are you having issues with the
system? Are you comparing it to a baseline you took when the servers were
originally created? Has the baseline been updated over time? Keep in mind
that default values in perfmon do not necessarily represent the best values
for your particular environment. Your pages may be completely normal for
your environment and unless you baselined the servers previously and can say
that on this date the pages were this and now they are this high, you really
have no idea if what your seeing is a problem.

thanks for your answer.
No, I don't have a baseline. the server is running fine but it does
look a bit "slow", even though task manager is not showing a high
usage of cpus and page file.
that's why I used perf mon. I have a battery of five terminal servers,
and on three of them there is a access application that seems to be
causing this pages/sec counter to be costantly over the top. the other
two terminal servers have this counter nearly at zero. I selected the
same counter (pages/sec) using the process counter and selecting this
particular process and again I see a high number of pages/sec, while
other applications (firefox, outlook, excel, etc) do not show this
behaviour....

do you have an idea of how to better troubleshoot this ?

thanks again for your help.

Hi,

Most likely you are seeing the result of the access .mdb file being
read into cache [Page In, a subset of Pages/sec]. How big is your
database files? Do people run queries frequently? Are these
queries performing well?

In task manager, is Commit Charge Total well below Physical
Memory Total? Is System Cache a large number as well?

When you have an application that does a lot of file i/o it is good
to have plenty of excess RAM that will go to system cache. That
is why I asked you if the commit charge is below physical. Depending
on your needs it may make sense for this to be several gigs below.

Thanks.
