Embodiments are directed towards improving the performance of network traffic management devices by optimizing the management of hot connection flows. A packet traffic management device ("PTMD") may employ a data flow segment ("DFS") and control segment ("CS"). The CS may perform high-level control functions and per-flow policy enforcement for connection flows maintained at the DFS, while the DFS may perform statistics gathering, per-packet policy enforcement (e.g., packet address translations), or the like, on connection flows maintained at the DFS. The DFS may include high-speed flow caches and other high-speed components that may be comprised of high-performance computer memory. Making efficient use of the high speed flow cache capacity may be improved by maximizing the number of hot connection flows and minimizing the number of malicious and/or in-operative connections flows (e.g., non-genuine flows) that may have flow control data stored in the high-speed flow cache.
