    Just curious if anyone noticed a significant performance degradation on the client side when the http servlet header decorator is enabled in your Java Agent Profile or CEM.


    Default is false.

    # Servlet Header Decorator

    # =======================================

    # On/Off Switch

    #

    # ================

    # If this Boolean value is set to true, it configures the agent to add

    # additional performance monitoring information to HTTP response

    # headers.  ServletHeaderDecorator attaches the GUID to each transaction

    # and inserts the GUID into an HTTP header, x-wily-info

    # This enables the correlation of transaction between Wily CEM and Wily Introscope

    1. introscope.agent.decorator.enabled=true

    We have been running the Servlet Decorator for three years and the additional header values of the x-wily* has not impacted performance to a point to be a leading issue/cause.

     

    Hope this helps,
