Logging Tuning

The following table describes logging tuning parameters and their settings.

Parameter	Settings	Impact
Disable logging when not needed.	Using Microsoft Management Console, navigate to the Web sites (virtual servers) under the IIS snap-in. Right-click Default Web Site and/or any other Web site(s) where your content exists, and click Properties. From the Web Site property page, clear Enable Logging to disable logging. Click OK.	This frees up system resources and provides better performance.
If logging is enabled, log to a striped partition with a controller that allows write-back caching, especially if you see heavy use on the log disk.	Using Microsoft Management Console, navigate to the Web sites (virtual servers) under the IIS snap-in. Right-click Default Web Site and/or any other Web site(s) where your content exists, and click Properties. Click the Web Site tab. Click the Properties button under the logging section. Make sure the path maps to a striped partition.	Busy sites can see the log disk become a bottleneck, because it is a point of contention. This means that all requests on the server will be contending for a single file.
