BLTHOST_MIN_WORKERPOOL_SIZE

The minimum number of worker threads that the thread pool creates on demand. The default is 0, which allows the call to SetMinThreads to be the number of processors on a system.

BLTHOST_MIN_IOPOOL_SIZE

The minimum number of asynchronous input-output (I/O) threads that the thread pool creates on demand. The default is 0, which allows the call to SetMinThreads to be the number of processors on a system.

BLTHOST_MAXCONCURRENTCALLS

Specifies the maximum number of messages actively processing across a BLTHost. The default is 16 times the processor count.

BLTHOST_MAXCONCURRENTSESSIONS

Specifies the maximum number of sessions a BLTHost object can accept at one time. It also sets the maximum number of queued connection requests that can be pending. The default is 100 times the processor count.

BLTHOST_MAXCONCURRENTINSTANCES

Specifies the maximum number of InstanceContext objects in the service that can execute at one time. The default is 116 (BLTHOST_MAXCONCURRENTCALLS + BLTHOST_MAXCONCURRENTSESSIONS) times the processor count.
