There are two primary ways to configure runtime behavior: CoreCLR hosts can pass in key-value string pairs during runtime initialization, or users can set special variables in the environment or registry. 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.
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 |
This table is machine-generated from commit ae2d2f3 on 04/20/16. It might be out of date.
When using these configurations from environment variables, the variables need to have the COMPlus_ prefix in their names. e.g. To set DumpJittedMethods to 1, add the environment variable COMPlus_DumpJittedMethods=1.
