The operating system on the host CPU determines which data to store in the cache and for which packets it should use data from the cache. To facilitate data reuse across multiple packets and connections, the cache only stores application-level response content (such as HTTP data), with application-level and networking headers generated by the host CPU. 1 INTRODUCTION WEB server performance has improved substantially in recent years, due mostly to rapid developments in application and operating system software. Techniques such as zero-copy I/O, and event-driven server architectures have reduced the CPU load, the amount of main memory used for networking, and the bandwidth requirements of data transfers between the CPU and its main memory. Web servers are now capable of achieving multiple gigabits per second of HTTP content throughput. As server performance increases, the local I/O interconnect within a server, such as the peripheral component interconnect (PCI) bus, has become a potential bottleneck. Network interface data caching can alleviate the local interconnect bottleneck by caching data directly on a network interface. The cached content is no longer transferred across the local interconnect. Instead, it is directly transmitted from the network interface, thereby reducing the interconnect traffic. The operating system on the host CPU determines which data to store in the network interface data cache and for which packets it should use data from the cache. Cach
