Understanding Exchange Workload Management with Exchange 2013

It optimizes the resource the utilization (CPU, Database RPC Latency etc.) for the users and system.

It performs this by assigning specific processes higher or lower (dependent on need) priority levels.

Typically a workload typically comprises of one of the following:
Exchange Server Feature: Mailbox Role
Exchange Service: OWA, ActiveSync etc.
Protocol: IMAP4, POP3 etc.

You also have the ability to control how users use recourses:
- Burst Allowances: Defines how much burst the user is entitled to until there connection is throttled.
- Traffic Shaping: Causes uses to have "micro-delays" when the server recourse limit hits a pre-defined value - lessening the load on the server before it gets worse.
- Maximum Usage: When a user exhausts the maximum usage limit, the recourse can be temporarily blocked.

To view a throttling policy you can use the "Get-ThrottlingPolicy" cmdlet:

Get-ThrottlingPolicy | Format-List

To view throttling policy associations you can use the "Get-ThrottlingPolicyAssociation" cmdlet:

Get-ThrottlingPolicyAssociation -ResultSize 10 | Format-List
