SMTP and POP3 workload
The SMTP and POP3 workload models an active user receiving and sending mail over SMTP and POP3. The script contains an average of 10 minutes of waiting, so an average user will run this test no more than six times an hour.
About this task
During each iteration, the script checks for and retrieves POP3 messages. When sending messages, each user sends a mail message to NumMessageRecipients not more than once every 20 minutes. Twenty percent of the users receive eighty percent of the send mail messages. The SMTP messages sent by each user are delivered to the mail databases of other users on the SUT.
The measurements obtained by this test are:
- Throughput of completed Notes® operations
- Average response time at maximum capacity
- Maximum number of SMTP/POP3 mail users supported
The resulting capacity metric for an SMTP/POP3 server is the maximum number of users that can be supported before the average user response time becomes unacceptable.
The following hard disk requirements apply to the SUT and, during some tests, to the destination systems that receive mail from the SUT:
| Setting |
Value |
|---|---|
Initial disk requirement |
In Domino® 6 or later, approximately 11.5MB on the SUT for each user (mail database). In Domino 5, approximately 7.5MB. |
| Subsequent disk requirement |
Increase of 100KB per hour for the duration of the test. This figure is not dependent on the number of users. |
