pMinPoolSize
- The minimal pool size. The pool will always keep at least this
number of worker threads alive even in no load situations.pMaxPoolSize
- The maximal pool size. The pool will create up to that number
of worker threads on heavy load.pToleratedBacklog
- The task backlog that is tolerated before an additional worker
is createdpToleratedIdle
- The idle time of a worker that is tolerated before the worker
is destroyedpGroup
- Then thread group to put the worker threads inpWorkerName
