| Abstract: | When the network load increases to a certain extent, data forwarding performance begin to decline on linux-based firewall system. The most common bottleneck is the consumption of system software interrupt on a single CPU approach 100%. This paper analyzes the problem and proposes an easy to implement and obvious solution to improve performance. |
