通过零拷贝实现有效数据传输

源:http://www.ibm.com/developerworks/cn/java/j-zerocopy/index.html

主要看代码就可以了.

public void testSendfile() throws IOException { String host = "localhost"; int port = 9026; SocketAddress sad = new InetSocketAddress(host, port); SocketChannel sc = SocketChannel.open(); sc.connect(sad); sc.configureBlocking(true); String fname = "sendfile/NetworkInterfaces.c"; long fsize = 183678375L, sendzise = 4094; // FileProposerExample.stuffFile(fname, fsize); FileChannel fc = new FileInputStream(fname).getChannel(); long start = System.currentTimeMillis(); long nsent = 0, curnset = 0; curnset = fc.transferTo(0, fsize, sc); System.out.println("total bytes transferred--"+curnset+" and time taken in MS--"+(System.currentTimeMillis() - start)); //fc.close(); }
