The minimum limit is a goal for how many threads the server attempts to keep in the WaitingThreads state. This number is just a goal. The number of actual threads in this state may go slightly above or below this value. The default value is 48. The maximum threads represents a hard limit for the maximum number of active threads that can run simultaneously, which can become a bottleneck for performance. The default value is 128.
Go to the Preferences tab.
Click the Performance Tuning link.
Enter the value in the Maximum simultaneous requests field.
