To avoid overloading the system (and causing connection
timeouts), you can stagger the number of users that start rather than starting
them all at once.
To stagger the starting times of virtual users:
- In the Test Navigator, expand the project until you locate the
schedule.
- Right-click the schedule, and then click Open.
- In the Schedule Element Details section, under User Load, check
the box Add a delay between starting each user.
- In Delay, enter a number and select a time
unit.
