Monitoring and Tuning Your Server

Analyzing the File System Cache Data

You can use the data you collect with PerfMon to evaluate whether your server has enough memory to support an effective File System Cache.

To evaluate server memory

1. Determine how the size of your server’s File System Cache varies over time.
2. Determine the extent to which cache performance varies with cache size.
3. Verify that the server has enough memory to support an effective cache even when the server is most active.

The following sections provide information to help you perform this evaluation:

• Analyzing Cache Size Data
• Analyzing Cache Performance Data
• Comparing Cache Size and Performance Data
