Turn on or off the HTTP request throttling job. This job monitors front-end Web server performance, and in the event of HTTP request overload, rejects (throttles) low priority requests. You can turn request throttling off to allow services such as Search to run uninterrupted on the farm, however, in an unthrottled farm experiencing overload, front-end Web servers become less responsive, and may stop working.
