| Abstract: | Asynchronous I/O is more efficient when applied to FTP service than synchronous I/O essentially. LINUX is supportive to asynchronous I/O on kernel-level under version 2.5,but many FTP services use synchronous I/O to access file as before. By replacing synchronous I/O by asynchronous I/O to store file to improve on FTP service, performance of FTP service is improved. Comparison experiment proves that asynchronous I/O has better performance. |
