The even-numbered hyper-threads (0, 2, 4, etc.) are dedicated to TMM as a high-priority process to service data plane tasks. The odd-numbered hyper-threads (1, 3, 5, etc.) process control plane tasks at a normal priority level. However, if or when TMM reaches 80% utilization, the odd-numbered hyper-thread throttles control plane tasks so they can only use 20%, allowing TMM to use the remaining resource.
