Windows2003: high swap file usage with 1GB RAM

Hi,


I have a customer running SBS2003 Standard SP1 on a Proliant ML350 G3, 3GHz,
1GB RAM, 2x72GB SCSI RAID 1.
The pagefile size is set to minimum & maximum 1536MB. It's on the C: drive.

The users (just 5 in total) were complaining that the system was very slow.
I ran "performance monitor" and noticed the following:
Memory \ Available MB: 618 MB
Paging File Usage \ %: 70 %
Cache \ Data Map Hits : close to 100%
Average disk queue length is close to 0, processor time about 5%,
Interrupts/sec are about 200/sec.

In task manager, I see Commit charge is 1400MB / 2470MB. No single process
is using more than 50MB, but there are about 100 running (most resource
intensive: SBS SQL monitoring, SBS Sharepoint SQL, WSUS, symantec AV,
Exchange)

If I understand this correctly, 70% of the pagefile (or 1075MB) is in use.
Thus, it appears to me only 1400 - 1075 = 325MB is in use by the real
physical system RAM.
Can I somehow force it to use the system ram first?


thx

David

I would not consider this enough ram for a server. Ram is cheap with all
things considered. Min would be 2gig. I routinely max out to 4gig for my
systems.
Memory \ Available MB: 618 MB
Paging File Usage \ %: 70 % This is good. Means its the right size.
Cache \ Data Map Hits : close to 100% This is good
Average disk queue length is close to 0, processor time about 5%, This is good
Interrupts/sec are about 200/sec. You want to monitor memory page faults. Lots of hard faults means add ram.

This is not where the slowness is coming from imo. Are these SATA drives?
How is the network setup? 100mb switch/nics for all? Everyone connecting at
100mb? What are they doing when they report slowness?

Off the top I would add ram and two drives mirrored for the data so you can
breakup the disk io which will improve disk performance.
