Ruby On Rails is a powerful framework for web development, but it can be difficult to optimize its performance. It is a powerful tool, but it can be slow if not optimized correctly. Performance optimization can help speed up your website or application and make it more responsive. As more and more businesses rely on their web applications for mission-critical tasks, it’s important to ensure that your Ruby On Rails application is running efficiently. 

Fortunately, there are several strategies you can employ to improve the performance of your Ruby On Rails application. From caching techniques to optimizing database queries and taking advantage of asynchronous processing, there are many ways to ensure your Ruby on Rails application is running optimally. In this article, we’ll discuss some of the best practices for optimizing Ruby On Rails performance.

Why There is Need to Optimize Ruby on Rails App?

Optimizing a Ruby on Rails application is essential for ensuring that it runs smoothly and efficiently. It can help improve the speed of your application, reduce memory usage, and provide better performance overall. It can also help you identify potential bottlenecks or problems with your code that may be causing performance issues. 

Furthermore, optimizing your Ruby on Rails application will ensure that it runs as quickly and effectively as possible in the long run. 

Optimizing the app can sometimes prove to be complicated and time-consuming. Also, you will need to know exactly why the app has low performance so as not to labor in vain. That is why seeking the expertise of professional developers is the best option. Sloboda Studio is a full-cycle software development company with over a decade of experience.

How to Improve Ruby on Rails App Performance

Let’s discuss improving Ruby on Rails app performance by taking advantage of these tools and techniques.

Server Optimization

When it comes to improving the performance of Ruby on Rails applications, server optimization is key. It can help you get the most out of your application and ensure that it runs smoothly and efficiently. 

Server optimization involves tweaking your server configuration, such as memory usage and disk I/O, to make sure that your application runs as quickly and efficiently as possible. 

Additionally, you can use caching techniques to reduce the amount of data that needs to be transferred between the client and the server. By optimizing your server configuration and utilizing caching techniques, you can dramatically improve the performance of your Ruby on Rails application.

Work on N+1 Query Problems

One of the most common performance issues is the N+1 query problem. This issue occurs when an application makes multiple requests to a database for data that could have been retrieved in one request.

To improve your Ruby on Rails app performance, it’s important to solve this problem by optimizing your queries and reducing the number of requests you make to the database. This can be done by using techniques such as eager loading, caching, and batching. 

By taking these steps, you can ensure that your Ruby on Rails app runs more efficiently and delivers better results for users.

Adding Indexes

Adding indexes is among the most important steps you can take to improve the performance of your Ruby on Rails app. Indexes allow for faster query execution, allowing your app to run faster and more efficiently. 

Use Background Job Processors

Background job processors help to offload long-running tasks from the main thread, thereby freeing up resources for other tasks. This helps to improve the overall performance of the application as it can process more requests in less time.

Background job processors also help to reduce latency and ensure that users are served quickly and efficiently. By using background job processors, developers can ensure that their application is running smoothly and efficiently at all times.

Cache Everything You Can

Caching allows developers to store data in memory so that it can be quickly retrieved without having to query a database or run complex computations. By implementing caching, developers can significantly improve the performance of their Ruby on Rails applications and make them more responsible for their users.

Use Ruby GC Tuning

Ruby GC Tuning is a powerful tool for improving the performance of your Ruby on Rails application. It enables you to optimize your application’s memory usage and garbage collection cycles, allowing you to achieve better performance from your web server and database. With the right tuning, you can significantly reduce the time taken for requests and improve overall responsiveness.

Get Familiar With CDN

A CDN is a network of servers located in different parts of the world that can store and deliver content faster than traditional hosting services. It works by caching static content such as images, videos, and JavaScript files so they can be delivered quickly to users around the world. By using a CDN, users will experience faster page load times and improved app performance.

Share Static Files

By sharing static files, you can reduce the amount of data that needs to be sent over the network and improve overall app performance. 

Additionally, it will also reduce server load and make your application more responsive. This article will discuss how to share static files in a Ruby on Rails application and how it can help improve performance.

Compress the Files

Compressing files can reduce their size, which in turn reduces the time it takes for them to load. This can make a huge difference in terms of page loading times, user experience, and overall performance. Additionally, compressing files can also reduce bandwidth usage and storage costs. Compression is an important step in optimizing your Ruby on Rails app performance and should not be overlooked.

Make Friends With AJAX

AJAX allows for asynchronous loading of content, which can drastically reduce page load times and make your application more responsive. Additionally, AJAX can reduce the amount of data sent over the network and help you keep your application secure. By leveraging the power of AJAX, you can ensure that your Ruby on Rails app runs smoothly and efficiently.

Final thoughts

It is no doubt that Ruby on Rails is a very popular development framework that enables developers to quickly build powerful applications. 

However, to ensure the best performance of your application, there are some steps you can take to improve its performance, such as caching strategies, database optimization, code refactoring and more.
