@ServiceHost Debug="true" - performance penalty?

Question

Is there a performance penalty of setting Debug="true" in the svc file? Is it significant enough to warrant setting it to "false" in a production environment?

%@ ServiceHost Language="C#" **Debug="true"** Service="AwesomeService" %>

Thanks

In your ".svc" file, if you are writing your service as inline code, or implementing service in "App_Code" folder and enabling debug mode, it will impact the performance.

Generally, always set debug="false" before you deploy to production. If debug mode is enabled, the performance of your application can be decreased.

In Release mode, the debug symbols are not baked into the assembly, so you cannot debug it using Visual Studio .NET or other source code debuggers. What's cool is that the code is also optimized during this build operation.
