Issue:
Currently we're dealing with an issue where SOAP requests to our production APM environment are taking a very long time to complete, causing timeouts within some of our systems.  Also see a slow connection to the APM UI  (ex. localhost:8081)
Environment:
APM 10.7
Cause:
This situation was caused because the customer had configured his Agents to connect the MOM on port 8081.

In the IntroscopeAgent.profile

agentManager.url.1=<MOM>:8081.

The Jetty webservice is configured to have 100 concurrent connection by default and this customer had many agent going to this URL.

This is a supported method to have an agent communicate with the mom the first recommendation is 

agentManager.url.1=<MOM>:5001

From more information please check out "Connect to the Enterprise Manager Using a Direct Socket Connection"
Resolution:
Customer revised configuration of his agents and SOAP and APMUI returned to normal.
