Limiting Active Requests by User

As System Administrator you can limit the number of requests that may be active (status of Running)
for an individual user. This ensures that a user cannot monopolize the request queue. For example,
if a user with an Active Request Limit of 5 submits 20 requests, only 5 requests will be run at the same time.
The remaining requests will be run when the number of active requests for the user drops below 5.
Use the Profile Options window to set the Concurrent: Active Request Limit profile.
To set a global limit for all users, set this option at the site level.
You can then modify limits for individual users by setting this profile option at the User level.
