Administering an ISP Installation

The following tips will help you to gain the maximum performance benefit from WCAT:

Because WCAT assumes that all clients are the same, and because it is also unable to recognize HTML code, you must spell out the contents of framesets and image URLs explicitly in your transactions, by clustering them under one class ID.
If performance suddenly improves, verify that an error has not occurred.
Turn off IIS logging while stressing your applications; otherwise, you’ll receive huge logs full of useless data.
