Cache.EffectivePercentagePhysicalMemoryLimit Property

Gets the percentage of physical memory that can be consumed by an application before ASP.NET starts removing items from the cache.

Namespace:  System.Web.Caching
Assembly:  System.Web (in System.Web.dll)

public long EffectivePercentagePhysicalMemoryLimit { get; }

Property Value

Type: System.Int64
The percentage of physical memory available to the application.

The EffectivePercentagePhysicalMemoryLimit property returns the percentage of physical memory that is available to the application. When the available percentage becomes low, the cache algorithm begins removing items from the cache.

The EffectivePercentagePhysicalMemoryLimit property can be set with the percentagePhysicalMemoryUsedLimit attribute of the cache Element for caching (ASP.NET Settings Schema) element in the application's configuration file. If the percentagePhysicalMemoryUsedLimit attribute is not set, the cache algorithm determines the maximum size of the cache, and the EffectivePercentagePhysicalMemoryLimit property is calculated.

EffectivePercentagePhysicalMemoryLimit is introduced in the .NET Framework version 3.5. For more information, see .NET Framework 3.5 Architecture.
