同Winsock1相比,最明显的就是支持了Raw Socket套接字类型,通过原始套接字,我们可以更加自如地控制Windows下的多种协议,而且能够对网络底层的传输机制进行控制。 1、创建一个原始套接字,并设置IP头选项。 SOCKET sock; sock = socket(AF_INET,SOCK_RAW,IPPROTO_IP); 或者: s = WSASoccket(AF_INET,SOCK_RAW,...

最后去msdn上查找raw socket时,找到了下面的描述(http://msdn.microsoft.com/en-us/library/windows/desktop/ms740548%28v=vs.85%29.aspx): Limitations on Raw Sockets On Windows 7, Windows Vista, Windows XP with Service Pack 2 (SP2), and Windows XP with Service Pack 3 (SP3), the ability to...

So again, DwarFS used less raw CPU power overall, but in terms of wallclock time, the difference is really marginal. With SquashFS & xz This test uses slightly less pathological input data: the root filesystem of a recent Raspberry Pi OS release. This file system also contains device inodes...
