Measures reported by Exc2013CompLatTest
Transport bottlenecks are one of the common reasons for poor user experience with the Exchange server. Frequent / prolonged breaks in email message flow end-to-end often results in delays/failures in the delivery of business-critical emails, thus impacting revenues, affecting user productivity, and escalating support costs. To ensure the speedy delivery of mails, latencies in mail flow should be proactively spotted and resolved. The Exc2013CompLatTest test helps with this.
This test auto-discovers all transport components engaged in mail flow. Then, at configured intervals, this test reports how long it took each component to process email messages, 90%, 95%, and 99% of the time. In the process, the test reveals latencies in message processing and accurately points to the transport components responsible for the same.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Per90_com_lat |
Indicates the maximum time taken by this transport component to process messages 90% of the time. |

If the value of these measures are consistently high for one/more transport components, it could indicate bottlenecks in email flow. The reason for the same has to be ascertained and resolved, so that there is an uninterrupted flow of emails end-to-end.
High latencies can be triggered by one or more of the following reasons:
- A networking issue exists.
- The Transport component of the Microsoft Exchange 2013 is under a heavy load.
- Some messages have been sent to large distribution groups.
- A Transport Agent issue exists. For example, the antivirus agent or Rights Management Services agent may be experiencing an issue.
