Insufficient physical memory (RAM) in the server is a common cause of a slow network. To determine whether your server has sufficient physical memory installed, check the amount of server memory currently available for disk cache.
Click the Health Monitor link in the navigation frame and view the Available Memory status and values.
If the status is Suspect or Bad, view the System Memory Information page to determine the source of the problem. View the System Memory Information by clicking the Available Memory link on the Server Health Monitoring page or clicking the View Memory Config link in the navigation frame.
View the General Information window and note the percentage for the Long Term Cache Hits.
If the percentage of Long Term Cache Hits falls below 90 percent, add more RAM to the server.
HINT: If you are unable to add more RAM now, a short-term fix can help. We suggest unloading unneeded NLMTM programs or removing DOS from memory. Remember that these actions treat symptoms only and are not long-term solutions.
