Golang Performance Comparison | Why is GO Fast?

We have talked about the Golang programming language and its cutting-edge, long-lasting potential for creating web applications and AI systems. However, according to research by the Sunbytes team, 71% of Go engineers create microservices, making them the second most popular development tool behind Scala. Gin is the most popular Go web framework. Golang does not compare favorably to Python or JS in terms of acceptance growth rate.

Golang has shown to be extremely helpful for creating simple microservices. Golang is a general-purpose programming language that is straightforward to learn and has a clear syntax, making it simple to create software that is dependable and effective. Golang is a unique language that offers top-notch memory safety and management features despite sharing a syntax with C.

Comparing Golang’s Performance to Popular Programming Languages

Golang vs Java

The popularity of Golang is primarily due to its performance. Many developers have compared Golang to its rivals and discovered that Golang has the quickest compile time. Here is a comparison between Golang and well-known programming languages.

Java's code must be converted to bytecode before it can be processed by the compiler since it is compiled on a virtual machine. It is a platform-independent language, although the compilation process is greatly slowed down.

Golang is directly compiled from the binary file rather than using a virtual computer to compile code. That is why it develops applications much faster than Java. Golang is significantly faster than Java thanks to its automated garbage collection.

One of the easiest ways to check the programming language performance is to try solving complex mathematical functions. This approach allows checking the memory management and time spent in solving the problem. Here is the Go vs Java benchmark conducted by the community:

Golang vs Python

The Go programming language uses "goroutines," or lightweight processes, in its workflow to manage dependencies effectively by interacting with collections of packages. This feature, which enables users to design stable and effective software, explains why the majority of developers favor Golang over Python.

Go is extremely fast. The performance is similar to that of Java or C++. For some use cases, Go is typically 40 times faster than Python. Here’s a small benchmark game comparing Go vs Python. Another Go vs Python benchmark:

Golang vs Node.js

Nodejs runs on Javascript, which is an interpreted language. This means that computation and raw performance can never match the speed of compiled language like Go. Go, an open-source programming language, on the other hand, is designed for high performance. Google made the decision to create the language only as a result of its frustration with the limitations of the current programming languages. They've obviously been successful. Go performs far better than Javascript and Node.JS.

Compared to Node.js' single-thread architecture, Golang's goroutines are quicker and more effective. Golang is the ideal choice for high-performance system design because they also let engineers deal with problems like network timeout and database failures.

 

Golang vs C

Go executables are typically slower than C executables when compiled. The fact that Go is completely garbage collected slows things down. With C, you have complete control over how much memory you want to allocate for the variables, including whether they should go on the heap or the stack. Go's compiler makes an effort to assign the variables in the most logical place possible. With the help of the go build -gcflags -m command, you can see where variables will be allocated, but you cannot make the compiler use only the stack, for instance.

But we also need to consider developer and compilation speed when talking about speed. Go offers incredibly quick compilation; for instance, 15,000 lines of Go client code compile in 1.4 seconds. Development is quicker thanks to Go's excellent concurrent execution design (goroutines and channels) and the fact that the comprehensive standard library mentioned above takes care of the majority of the fundamental requirements.

Here is a benchmark comparing Golang vs C:

Why is golang fast?

Statically typed language, compiled langue

Go is a statically typed language. A statically-typed language is a language (such as Java, C, or C++) where variable types are known at compile time. In most of these languages, types must be expressly indicated by the programmer; in other cases (such as OCaml), type inference allows the programmer to not indicate their variable types. This helps to mitigate runtime errors. It also means that the code is easier to understand and build on

Go is a compiled language. This means we must run our source code files through a compiler, which reads the source code and generates a binary, or executable, file that is used to run the program. Examples of other popular compiled languages include C, C++, and Swift. Programs written in these languages are transformed into machine code and can perform extremely fast.

 

Concurrency

Programmers coming from single-threaded scripting languages like Node.js, Ruby, or Python or from languages like C++ or Java with their complex threading models find Go's concurrency primitives appealing. Golang programs can handle concurrency for less money by using goroutines. If not adequately maintained, they might have a high memory footprint. Performance decline can result from improper goroutine management.

 

A simple, light-weight programming language

Go is relatively simple, lean, and minimalist: For instance, Golang has just 25 keywords. One of the design decisions made when developing Golang was to make it straightforward and simple to learn. There is hardly any clutter or complexity. But it also made the compilation process speedier.

 

Efficient Dependency Analysis

Only the packages you directly imported into the Go file will be included by Go. There are no headers like in C/C++. Even parsing the massive number of headers present in every line of C/C++ code takes a long time.

 

Summary

Golang is incredibly adaptable and looks to be very promising. Many businesses use it to boost productivity and improve the performance of their products. Furthermore, it is the ideal language for avoiding scalability constraints because of its goroutines that handle concurrency concerns.
