IIS6 server memory paging

Hi all,

I have a problem with some of our webservers.
In the performance monitor I can see there is a lot of paging going on.
The websites that are running on these machines are classic ASP websites and
they are using msxml4 with the latest SP.

The server is a:

Windows 2003 SP2
Dual Xeon 2.4Ghz
2GB RAM

I created the screenshots just after a reboot so there's not much memory in
use yet but it's already paging like crazy...

Screenshot2: http://www.datasmit.nl/temp/screenshot2.jpg

Does anyone know how I can check what is causing this much paging?

Thanks in advance

Re: IIS6 server memory paging

It sounds like some process is doing Disk I/O intensive. It could be
creating images, PDF files or something disk related. You have plenty of
memory available. I would also check your page file setup. Make sure it is
1 1/2 times the size of ram.

Re: IIS6 server memory paging

Hi,

We do nothing with the filesystem other than get the website images etc, and
these are on a NAS.

The page file is managed by the OS, it currently has 2GB allocated on the
first drive and 2GB on a second drive.

As you can see there is plenty of RAM so I don't know why it's paging to
disk.

Is there maybe a tool that can see what is doing all the paging?
The only thing I can think of is that the MSXML4 tranformations are paging
but why?! The xml is in memory and the xsl is located on the NAS.

Thanks
