DotNetNuke offers support to allow for great performance in a variety of hosting environments. This ability of DotNetNuke is enabled by the robust set of configuration settings that are made available, in addition to configuration there are certain administration practices that can impact performance. The following sections outline these areas.

Host Settings - Performance Settings

The most basic performance related configuration settings are the ones contained within the Host Settings -> Performance Settings section. These are settings that control the way that pages are cached and served by the DotNetNuke installation. The following is a listing of the settings available.

Performance Setting Options

Setting	Function	Note
Page State Persistence	Controls where ASP.NET viewstate is stored. Page size will be reduced if "Memory" is selected.	This setting should be left at page, as the memory option can cause issues with a number of situations.
Module Caching Method	Controls where module cache items are stored	Memory is faster, disk is better if resource constrained
Performance Setting	Controls how much caching is done.	Heavy provides the highest level of caching.
Authenticated Cacheability	What should the cache setting be for authenticated users/content
Compression Setting	Allows configuration of compression for sending contents to the user. GZip compression is most common.	If compression is enabled, Whitespace Filter shouldn't be on.
Use Whitespace Filter	If enabled, whitespace will be removed from generated content, reducing page size.	Should not be used if compression is used.
