You can reduce the level of intrusiveness of garbage collection in your application by setting the System.Runtime.GCLatencyMode to GCLatencyMode.LowLatency during critical operations. After such operations are completed, return to a higher latency mode so that more objects can be reclaimed to increase memory.

See Latency Modes for a discussion of how the runtime configuration settings for garbage collection affect the default value of the System.Runtime.GCLatencyMode enumeration.
