Top 15 Tips And Tricks To Improve Performance Of Golang Application

With the advancement of technology, everyone wants a speedy application, users need speedy delivery, developers want fast performance, and entrepreneurs want both. Here comes the need to optimize your app performance. You need to improve speed and performance of the app to make it best in the market. There are two main reasons for which you want to optimize your golang app- For resource efficiency, for improving operation latency. Your application should be with the end goal that it doesn’t need so many resources that it continues waiting for the operation. Whereas, your Golang app is too complicated that to execute one of its tasks, it has to rely on another, and in this way, it becomes a dead-end loop of dependencies. Here we’ll discuss some best practices to improve the performance of golang app. But before this, let’s see some tips to opt before optimizing app performance.

Tested Performance Tips-

Latency Optimization-

Here you need to analyze the bottlenecks of program. Main aim is to optimize a particular function’s latency. As you improve resource efficiency of program, latency is automatically improved. Whereas, improving latency may demand increased resource consumption. You must be conscious of both-program bottlenecks and hot spots and simultaneously work on them.

Resource Efficiency Optimization- 

You enhance app performance to optimize resource use. Some of the parts of program need more resources than others, and you should find such hot spots for your app program. It can be CPU, bandwidth,or memory.

Algorithm Efficiency-

Program has some ways of varying magnitudes to execute same operation. By implementing algorithm optimization, you can maximize performance of app.

So as to improve the speed of golang app, you need third-party tools and built-in packages for optimization. So here we’ve collected best practice. Let’s see each one in detail.

Tips And Tricks To Improve Performance Of Golang Application–

1. Parallelize CPU Work-

Synchronizations takes a huge time and when you parallelize work by using available cores, it will surely optimize the golang app performance. This is an important step to speed up app execution linearly.

2. Observe Your Timeouts-

Generally input output operations takes more time that leads to latency. To overcome this, you should avoid any I/O task without knowing the time that it will consume. You should use SetDeadline, SetReadDeadline and SetWriteDeadline before setting a timeout on each network request.

3. Make I/O Operations Asynchronous-

Most common bottlenecks that arises because of network transactions and file input/output executions. Hence, to optimize your golang app performance, you can make independent I/O asynchronous. In this manner, such operations run in parallel and improve downstream latency. Also, you can use sync.WaitGroup to synchronize multiple I/O operations.

4. Reduce The Use Of Goroutines-

Availability of using Goroutines is the feature that makes Golang a valuable programming language. It is very cheap and easy to use that makes us feel that it is almost free. BUt goroutines do cost a significant memory footprint that affects app performance. Usually, Go developers create infinite goroutines without calculating or knowing when they will exit. So, it is recommended that you start a goroutine only if you know when it exits.
