My server is Windows 2003 co-exist with SQL2000 database, this is a web application server. I was told that when more user access to server, they reported that the speed is very slow. This server has 3GB RAM and P4 Xeon 2.4GB CPU and equipped with one 10Krpm SCSI harddrive. When I use the windows performance counter log to check it, I found it everything is normal. What else can I check to find out why the response is slow.
