The problems of optimizing the memory copy for device driver program and zero copy technique are discussed.

进一步讨论了驱动程序的内存拷贝优化问题和零拷贝技术。

After analyzing the test data, it concludes that the performance of Ethernet adapter driver is improved by both optimizing the memory copy and adopting the zero copy technique.

通过测试数据分析得出优化内存拷贝和使用零拷贝技术都能提高网卡驱动程序的性能。

Now using "zero copy" to improve this process: When the net card will catch the data packet later directly to write about the sharing memory, such treating processes reduced at least duplication.

利用“零存储”技术对传统的抓包过程进行改进：当网卡抓到数据包以后直接写到共享内存，这样的一个处理过程减少了至少一次复制。
