Testing has also measured very low latency of 30 microseconds for 120-byte messages delivered at 10,000 messages per second on InfiniBand or 61 microseconds on Ethernet.
After the stop bit is received, the device will acknowledge the received byte by bringing the Data line low and generating one last clock pulse.
在收到停止位之后，设备将通过拉低数据线，生成最后一个时钟脉冲来应答收到的字节。

It's hard to get worked up about still dealing with low-level, per-byte-precise entities like pointers and C structs when your application is constantly receiving low-memory warnings from the OS.
当你的程序持续不断的收到系统发送的低内存警告；当你不得不与低级语言、字节级精度的指针与 C 结构打交道的时候，你怎么嗨的起来？
