Memory Utilization
Memory activity was monitored using the Microsoft Performance Monitor.
Memory – Pages/Second
The Pages/Sec counter gives the number of pages read from or written to the
disk to resolve references to pages that were not in memory. This is the
primary counter for determining whether the server is paging excessively (or
“thrashing”).
The highest acceptable value for Pages/sec varies from system to system.
One way to determine whether system load is causing too much paging is to
observe whether processor activity (System - %Total Processor Time) drops
significantly as paging increases. This may indicate that the system is
occupied with swapping pages rather than performing “real work”.
Memory – Available Bytes
The Available Bytes counter displays the amount of free physical memory.
If the Memory - Pages/sec counter is increasing, yet the Memory - Available
bytes counter is not decreasing then memory may not be a bottleneck. In this
situation, an application may be issuing a significant number of requests for
new, non-cached data.
Memory – Committed Bytes
The Committed Bytes counter records the amount of virtual memory that has
been committed to either physical RAM or the pagefile. If the amount of
committed bytes is larger than the amount of physical memory, it may
indicate that more RAM is required.
