Guest zerbie45@gmail.com Posted July 17, 2008 Posted July 17, 2008 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! zz
Guest Jeff Pitsch Posted July 17, 2008 Posted July 17, 2008 Re: terminal server 2003 perfmon pages/sec 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.

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. zz
Guest TP Posted July 17, 2008 Posted July 17, 2008 Re: terminal server 2003 perfmon pages/sec 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.
