Today, the set of configuration options that can be set via the former method is relatively small, but moving forward, we expect to add more options there. Each set of options is described below. + +## Host Configuration Knobs + +These can be passed in by a host during initialization. Note that the values are all passed in as strings, so if the type is boolean, the value would be the string "true" or "false", and if it's a numeric value, it would be in the form "123". + +Name | Description | Type +-----|-------------|------ +System.GC.Concurrent|Enable concurrent GC|boolean +System.GC.Server|Enable server GC|boolean +System.GC.RetainVM|Put segments that should be deleted on a standby list for future use instead of releasing them back to the OS|boolean +System.Threading.ThreadPool.MinThreads|Override MinThreads for the ThreadPool worker pool|numeric +System.Threading.ThreadPool.MaxThreads|Override MaxThreads for the ThreadPool worker pool|numeric + +## Environment/Registry Configuration Knobs + +This table is machine-generated from commit 82ed770 on 05/31/16.
