84 Optimizing IBM Netfinity Servers for SAP R/3 and Windows NT
2.13.7.3 Allocation of Server Memory
Windows NT will allocate as much as half of the system main memory to a disk
and file cache. As a result, the operating system must often swap memory pages
to disk in order to allocate enough physical memory to run new processes.
The allocation of real memory to the disk cache can be indirectly controlled by
specifying how much memory to give to the server processes.
To do this:
• Open the Control Panel.
• Open the Network folder.
• Select the Services register tab.
Figure 46. List of Windows NT Network Services
• Double click in the Network Services List on the Server service. You will see a
dialog box like the one in Figure 47.
When specifying a page file size, increase the minimum value to
equal the maximum value. When the page file needs to grow past
the minimum value, it will slow down your server in the process. By
setting both values equal, you will waste some disk space but the
system does not need to spend time sizing the page file. If, on the
other hand, the page file partition has decreased in size since the
maximum size value was set, and this partition does not contain
enough disk space when the page file is expanded, NT will fail with
some odd results.
