Native Layer 7 services are an extension of Force Layer 7 services with the difference being that some Layer 7 functionality has been enabled. Regardless of whether Layer 7 persistence, caching, IPS or Content Switching is enabled, the LoadMaster must be observing the client-server interactions in order to follow the conversation and be an effective Layer 7 device. This naturally increases both CPU and RAM usage due to the processing and tracking components of this role.
