Performance Analysis of System Overheads in TCP/IP Workloads

Overview Current high-performance computer systems are unable to saturate the latest available high-bandwidth networks such as 10 Gigabit Ethernet. A key obstacle in achieving 10 gigabits per second is the high overhead of communication between the CPU and network interface controller (NIC), which typically resides on a standard I/O bus with high access latency. Using several network-intensive benchmarks, the impact of this overhead is investigated by analyzing the performance of hypothetical systems in which the NIC is more closely coupled to the CPU, including integration on the CPU die. It was found that systems with high-latency NICs spend a significant amount of time in the device driver. NIC integration can substantially reduce this overhead, providing significant throughput benefits when other CPU processing is not a bottleneck.
