Embodiments of the present invention provide a system for increasing processing efficiency through automated resource field transformation. A message with multiple resource fields is received, and a first resource field is identified as being populated with a burdensome resource element. The burdensome resource element is extracted from the first resource field, creating a slim version of the message that is processed through normal procedures to execute an associated event. The burdensome resource element is routed to a burdensome resource processing system. The burdensome resource processing system can store the burdensome resource element until the burdensome resource element is requested by a user, and then transfer the burdensome resource element to the user after specialized processing of the element. Alternatively, the burdensome resource processing system may be a specialized processing system that processes the burdensome resource element's type more efficiently than the general processing procedures used to process the slim message.
