--w min[,max[,timeout]]
-
-            Start at least min but no more than max worker threads
-            with the specified idle timeout.  This is a shortcut for
-            specifying the thread_pool_min, thread_pool_max and
-            thread_pool_timeout run-time parameters.
-
-            If only one number is specified, thread_pool_min and
-            thread_pool_max are both set to this number, and
-            thread_pool_timeout has no effect.
