When executing serial requests, the SQL Server Database Engine spawns a worker to execute the active task (1:1). Thread pooling enables you to use threads more efficiently by providing your application with a pool of worker threads that are managed by the system. The busy () function can be used in a while loop, such that the main thread can wait the threadpool to complete all the tasks before calling the threadpool destructor. The specific thread pool queue size can be changed using its type-specific parameters. thread_pool_transaction_delay : The delay period before starting a new transaction. Using thread pools we create a predefined number of threads which can be used and allotted tasks an innumerable number of times thereby reducing the overall thread cycle overhead.
