Issue/Introduction

After enabling Browser Agent,   started receiving performance based alerts from one of the URLs we synthetically monitor for an application.

Cause

Per engineering, test done with introscope.agent.bizRecording.enabled=false and the performance issue was also not reproduced.
And browser cache is not enabled. 

Environment

Release : 10.7.0

Component : APM Agents

Resolution

1. Disable bizRecording property on the Agent Profile. 
 introscope.agent.bizRecording.enabled=false and the performance issue was also not reproduced

2. Ensure the browser cache is enabled and the BA snippet captured in the browser developer tool has "async" enabled for the BA script tag as well, e.g. 
 

<script type="text/javascript" id="ca_eum_ba" src="https://browseragent.broadcom.com/api/1/urn:ca:tenantId:default-tenant/urn:ca:appId:default-app/bajs?agent=browser" data-profileUrl="https://browseragent.broadcom.com/api/1/urn:ca:tenantId:default-tenant/urn:ca:appId:default-app/profile?agent=browser" data-tenantID="default-tenant" data-appID="default-app" data-appKey="b03dlo800-4736-11f6-b8e5-cjjk75280658" async ></script>
