GCLatencyMode Enumeration

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Adjusts the time that the garbage collector intrudes in your application.

Namespace:  System.Runtime
Assembly:  mscorlib (in mscorlib.dll)

public enum GCLatencyMode

Member nameDescription
BatchDisables garbage collection concurrency and reclaims objects in a batch call. This is the most intrusive mode.

This mode is designed for maximum throughput at the expense of responsiveness. 

This mode overrides the [503f55ba-26ed-45ac-a2ea-caf994da04cd] runtime configuration setting. If [503f55ba-26ed-45ac-a2ea-caf994da04cd] is enabled, switching to Batch mode prevents any further concurrent collections.

InteractiveEnables garbage collection concurrency and reclaims objects while the application is running. This is the default mode for garbage collection on a workstation and is less intrusive than Batch. It balances responsiveness with throughput.

This mode is equivalent to garbage collection on a workstation that is concurrent.

LowLatencyEnables garbage collection that is more conservative in reclaiming objects. Full collections occur only if the system is under memory pressure, whereas generation 0 and generation 1 collections might occur more frequently

This mode is not available for the server garbage collector.

SustainedLowLatencyEnables garbage collection that tries to minimize latency over an extended period. The collector tries to perform only generation 0, generation 1, and concurrent generation 2 collections. Full blocking collections may still occur if the system is under memory pressure.

You can adjust the intrusiveness of garbage collection in your application by setting the LatencyMode property to one of the enumeration values.

See [96278bb7-6eab-4612-8594-ceebfc887d81] for a discussion of how the runtime configuration settings for garbage collection affect the default value for this enumeration.
