This paper presents the design of an Extra Performance Architecture for Delta-4 which explicitly supports the requirements of real-time systems with respect to throughput and response. The problems of replicate divergence are discussed, and a solution based on message selection and pre-emption synchronization messages is proposed. The paper includes a description of the on-going implementation of such system within the overall Delta-4 framework.
