I am very sad to write this short article about some understandings of network transmission. How to transmit data quickly between multiple nodes was just optimized from the perspective of data transmission, it would be a pity to give me another chance... Let's talk about the following points: first, we should try to improve the degree of parallelism, and each node transmits data to other nodes that do not have data in parallel (it was not clear at the time that this was probably despised) second, there is no limit to the bandwidth between network nodes. Therefore, data compression on the CPU end and transmission can improve the efficiency by more than half (Damn it, I forgot it at the time ), the accumulative transmission mode is also used, which is similar to the nagle algorithm to improve data transmission. You can modify the transport layer protocol, use udp for transmission, or customize the Protocol (difficult ). Author paramore
