Web开启TCP_NODELAY有类似的效果，但对于小的写入来说，可能会使吞吐量变差。但对于小规模的写入来说，吞吐量会变差。如果你写一个循环，用 "write() "向套接字发送几个字节（最坏的情况是一个字节）到一个套接字，而Nagle 算法被禁用，每次写入都会变成一个IP ... WebIf you use the tcp_write function, the maximum length is limited by snd_buf (send buffer length). send is a socket interface wrapped by lwIP based on the sequential API, which is a higher-level interface than tcp_write and is more suitable for user-level calls. There is basically no difference in resource usage between the two API calls.
