A brief analysis of the number of bytes related to golang

Go language (also called Golang) is an open source programming language founded by Robert Griesemer, Rob Pike and Ken Thompson who work at Google. It is popular because of its simplicity, ease of learning, good concurrency and high performance.

First of all, let’s talk about the number of bytes occupied by the golang code itself. Golang is a statically typed programming language, and its compiled product is an executable file. When compiling, the golang compiler will compile the code into binary form. The size of the generated executable file will be affected by the size of the code itself, the size of the dependent package and the compilation parameters. In general, golang code is relatively compact, and the size of the executable file is also relatively small, usually between tens of MB and hundreds of MB.

Secondly, golang also performs well in network communication. The golang standard library provides support for multiple network communication protocols such as TCP, UDP and HTTP. When a network communication program written in golang sends and receives data, since the bottom layer of golang uses byte slices to store and transmit data, the network communication process will involve the transmission of a large number of bytes. If you use a TCP server written in golang, when each client connects to the server, a buffer will be allocated in memory to store the data sent by the client. Ultimately, the performance of golang network communication programs mainly depends on network bandwidth and hardware device performance.

In addition, golang also has the so-called slice type, which is a slice type. A slice is a reference type. The underlying implementation is a structure containing three pieces of information, namely a pointer to the corresponding array, Slice length and slice capacity. When using golang for slicing operations, the underlying array is generally not copied or copied, so it is more efficient in memory usage and allows programmers to quickly perform efficient binary operations.

In short, the design and implementation of golang make it perform well at the byte level and network communication. At the same time, the innovative slice type also allows developers to operate more conveniently and efficiently in underlying data interaction.
