摘要
针对服务器的网络性能,提出并实现一种基于Linux内核的改进方案——ONPK。该方案通过减少系统调用和数据复制、改写网卡驱动来实现网络性能的优化。实验结果证明,该方案能明显改善服务器的网络性能,在保持发送速度有所提高的情况下,CPU的使用率平均可降低11%。
Aiming at the network performance of service, this paper proposes and realizes an improved scheme based on the Linux kernel called ONPK. In order to optimize the network performance, it cuts down the times of system call and reduces the times of data copy, changes the way of sending data by rewrite the NIC driver. Experimental results show ONPK can improve the network performance apparently, and reduce the CPU utilization for 11% averagely with a little increase of the sending rate.
