Message optimization method with low latency bypass

The invention discloses a message optimization method of low delay bypass. The method adopts a bypass mode, and adopts a fast bypass mode to process a user message request satisfying a certain lengthrequirement so as to reduce the calling level of a user function to a bottom message operation. At that same time, the packet operation is not carried out on the user message data and the packet headin the communication support environment, but the information is directly written into the short message path entries of the network interface chip, thereby reducing the transmission startup overheadof hardware read descriptors and accessing the us data. The invention can fully utilize the short and fast message path of the bottom hardware, reduce the hardware processing overhead, reduce the start-up and processing overhead of the message data from the software level as far as possible, and effectively reduce the short message communication delay. 本发明公开种低延迟旁路的消息优化方法，该方法采用旁路方式，对于满足定长度要求的用户消息请求，采用快速旁路方式处理，减少用户函数到底层消息操作的调
