Which limitation of CoreXL is mitigated by using Multi-Queue?

The correct answer highlights the way Multi-Queue technology enhances the performance and efficiency of traffic processing in environments using CoreXL.

CoreXL is designed to maximize the use of CPU resources for firewall processing by allowing multiple cores to handle different connections and flows across the system. However, a common limitation in traditional setups is the handling of traffic queues; specifically, if a single NIC is constrained by a single queue, it can lead to potential bottlenecks where one CPU core becomes responsible for all packets transmitted through that queue.

By implementing Multi-Queue, each NIC is configured to manage several traffic queues rather than just one. This allows multiple CPU cores to process packets simultaneously across these various queues, leading to better load distribution and improved performance. Essentially, this multi-queue model enables the system to utilize its resources more effectively, reducing latency and increasing throughput.

The improvement offered by Multi-Queue overcomes the restriction that each NIC is limited to one traffic queue managed by a single CPU, enhancing the overall efficiency of packet processing in the network security infrastructure.
