Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Active client logons	The number of active client logons into the Information store.	Number
Client logons	The number of clients logging into their Information store.	Number	This measure is a good indicator of user activity in the Exchange Server. This information can be used by the administrator for planning the capacity of the mail server.
Mail send queue size	The number of messages currently in the send queue of an information.	Number	This measure is usually zero under normal conditions. This measure can be non-zero in the case of very busy systems (2000 users and more).
Mail received queue size	This measure shows the number of messages currently in the receiving queue of the information store.	Number	This measure is usually zero under normal conditions. A non-zero value for this measure indicates that the SMTP service is choking up memory.
Mails opened	This measure indicates the rate at which the requests to open the messages are being submitted to the information store.	Msgs/Sec	This measure shows the overall picture of user activity. An abnormally high value for this measure may indicate that the Exchange 2000 Server is overloaded.
Avg mail delivery time	This measure indicates the average time between the submission of a message to the information store and the submission to other storage providers for the last 10 messages.	Secs	A non-zero value for this measure indicates a change in user workload. An abnormally high value for this measure indicates inability to deliver to one or more destinations. One of the possible reasons for this can be a network failure.
Avg local mail delivery time	This measure indicates the average time between the submission of a message to the information store and the delivery to all local recipients (recipients on the same server) for the last 10 messages.	Secs	A non-zero value for this measure indicates a change in the user workload. An abnormally high value for this measure may indicate that the server is overloaded.
