The main problem we had were around high memory usage because a lot of the more front end guys didn’t understand how the threading and multi-tenant modeling worked. Rust is not suitable for developing REST APIs, at least not as easily as with Go or even Python. Rust is very cool for developing low-level tools with increased control of memory management, in the case of low CPU cost applications. Rust is cool for memory management and why not low level development like in Linux kernel. But it’s way more complicated than Go to develop such http service. Instead of switching to rust, I prefer to ask to Go creator to help on fixing garbage collection control.

On top of being easy to learn, Go continues to outpace Java in the 2020 Stack Overflow survey, beating it in the ‘most loved’ and ‘most wanted’ categories for languages among developers. So, beginners learning Go are well positioned to succeed. Deciding which language is best for professional use depends on what kind of websites or applications you’re developing.

I did something like that earlier between Java and Rust. Where for cpu it was pretty comparable, but memory use with Rust was much lower. But when we develop an HTTP application with a very complex management of coroutines to manage SSEs, with messages coming from different routines, Rust becomes purely and simply infernal.

I hope next time you will also include V-lang in this comparison chalange. Perhaps results will be similar but this Lang is really worth to look at. Suggests that something is way off either with your project loom java setup or your code. Async Rust and async Go are capable of running hundred thousands concurrent connections. It might be interesting to also measure the resource use while the test is running.

Candidates include Java server software like Tomcat, Undertow, and Netty; and web frameworks like Spring and Micronaut. I expect most Java web technologies to migrate to virtual threads from thread pools. Java web technologies and trendy reactive programming libraries like RxJava and Akka could also use structured concurrency effectively. This doesn’t mean that virtual threads will be the one solution for all; there will still be use cases and benefits for asynchronous and reactive programming.

Not saying it is impossible, but differences in server implementations small like that are very unlikely. Anyway, what I’m trying to say is that I look forward to an investigation into other metrics beyond “requests-per-second”. As https://globalcloudteam.com/ Discord’s engineering team has shown, this does not always paint the full picture. Data on CPU and memory usage would definitely make your series more comprehensive. Java is generally utilized for building Android applications.

To boot, several elements of the language’s architecture promote its usage in networking and multiprocessing use cases. In the case of cross-platform development, you might benefit from choosing Java over Golang. You won’t write your mobile app with Go, but you can still benefit from using it for the backend due to all the reasons we’ve already mentioned. We’re big fans of Go here at boot.dev, which is why we created our Learn Go courses to help programmers learn Go and take advantage of all its benefits. In the end, a comparison of Go’s and Java’s memory usage, when sitting idle, showed Java consumed upwards of 160 MB of memory, while Go only used 0.86 MB – an insane difference.

It also has a strong community that provides assistance, tools, and tech stacks to create complex servers quickly. The biggest selling point of Rust is IMHO fearless concurrency with guarantee for no data races. So while Go programs may appear initially simpler to write, because they give a bit more freedom to a programmer, at the end of the day they are often not as easy to reason about. Fixing a compile time error vs fixing code failing once a week in production under heavy load only – the choice is pretty obvious to me. Java used to be the language of choice for server-side applications, but it no longer holds that position. Despite that, hundreds of various applications around the world employ it.

Both Java and Go can serve for cross-platform development. Both will require additional solutions to run the code. We’ll explain the details in one of the following paragraphs.

Debugging is essential to the success of your project as it enables fast identification and fixing of glitches in the app. Testing frameworks contribute to reducing the maintenance costs due to automation of the processes. There is almost no manual intervention necessary, and the testing is more accurate. Both Java and Go are multithreaded, which means they can execute multiple tasks within one process. Note, however, that Go wins in this competition due to better efficiency. That makes it the perfect choice for processor-intensive operations such as search algorithms in apps.

Note that making a server framework with a specific programming language isn’t the final turning point. You can generally change to another in transit when it’s the ideal opportunity for increasing. Not every programming language out there is suitable for every job, but there are languages like Java that can be used for many purposes. Golang is used for Distributed network services, Cloud development, etc. Java is a popular programming language and has a community of thousands of developers, Go language also growing rapidly and gaining popularity as it is fast and reliable. Go is faster than Java as it doesn’t rely on a virtual machine to compile its code, unlike Java.

Java in web & mobile development

Spring also works out the HTTP error responses automatically, while with Go, developers need to take care of it on their own. Using Java shortens the configuration process to an absolute minimum. The variety of handful frameworks makes building backend infrastructure less challenging. The brightest star among them is undoubtedly Spring – a set of libraries and tools that make coding simpler and less repetitive.

Being an Object-Oriented Programming Language, Java develops the OOP application relatively easier than Go and other programming languages. Java advances the extensibility and flexibility of the system and makes it modular. I would recommend also testing servers using one computer as client and another as server.

Virtual threads could be a no-brainer replacement for all use cases where you use thread pools today. This will increase performance and scalability in most cases based on the benchmarks out there. Structured concurrency can help simplify the multi-threading or parallel processing use cases and make them less fragile and more maintainable.

On the off chance that it doesn’t sound familiar, stress not – this language doesn’t stand out enough to be noticed external the engineer local area. An outcome is that they realize that their frameworks don’t bring any added value anymore and are just duplication. They stop their development effort, only providing maintenance releases to existing customers. They help said customers to migrate to the new Thread API, some help might be in the form of paid consulting. In this post, I’d like to dive a bit into the reasons that lead me to believe that. Go is automatically inlining fun() and unrolling the core loop.

And unlike most programming languages, Go’s syntax does away with brackets, parentheses, and those cumbersome colons programmers would often need to put at the end of lines. And now it is one of the fastest and most scalable programming languages there is. Golang advantagesGoogle wrote Go for its own purposes before releasing it to the public a few years later in 2012. Since the beginning, it’s been described as a simplified language addressed to developers with little experience. As a result, it cannot boast quite such a broad application in commercial projects. It also has a large community that brings endless support, as well as tools and tech stacks that allow you to code complex servers in a stitch.

Spring likewise works out the HTTP mistake reactions naturally, while with Go, designers need to deal with it all alone. Utilizing Java abbreviates the design interaction to an outright least. The assortment of modest bunch systems makes building backend framework less testing. The most splendid star among them is without a doubt Spring – a bunch of libraries and apparatuses that simplify coding and less dull. As an item arranged, definitive language, Java is ideal for complex activities, where scrupulousness and adaptability isn’t really the primary concentration. The goal of Project Loom is to actually decouple JVM threads from OS threads.

Java’s lack of performance is partly due to its virtual machine for Java compilation. Though it allows Java to run on any platform, this virtual machine reduces its speed. In addition, the concurrency of Golang is also an essential characteristic. ‘Goroutines’ allows functions or procedures to run parallel with each other. Java has multithreading capabilities that provide a similar effect, although significantly less powerful than Golang’s. Java has been around for a long time, curating its position as a powerhouse in the software industry for backend development.

That isn’t the situation with the code written in Go, which consistently boils down to a parallel. Aggregating the different double records for every stage can be tedious and influence the productivity of the undertaking. We should not disregard the simultaneousness perspective – the capacity of the language to run a few cycles freely of one another.

On the flip side, it uses other kinds of resources, in particular memory. Java language is an object-oriented language, on the other hand, Golang doesn’t support classes and objects. Go is a simple and scalable language which means it is easy to learn compared to Java language. After running the count in your head, you may have just realized that there’s no objectively better language as far as the side-by-side comparison is concerned. For instance,Go compiles code into a binary file for any given platform.
