Maximum Load Average

Syntax: number, or -1 for no limit

Maximum Load Average helps prevent the Search Appliance from becoming overloaded. If the load goes above the specified Maximum Load Average, the walk will pause itself until the load decreases.

You can see the current load of the appliance at any time by going to System → System Information, next to Load. The 3 numbers represent the average load during the last 1, 5, and 15 minutes.
