It is an open-source framework with an object-oriented programming (OOP) structure, known as an efficient web development tool. It has a multi-layered functional structure with the Model, View, and Controller components similar to those of many other web development frameworks. It is well known for its speed in the development process. Besides, excellent serve performance can be achieved by using Ruby on Rails.

Rails makes a perfect match for experts and novices alike. It equips developers with a set of unique features , suitable to address complex problems of experts with the help of simplified solutions.

Performace Optimization

Choose your hosting provider wisely

Web hosts offer important services like server management and backups. Choosing the right hosting provider is important for any app – not only one built with Ruby on Rails – as it influences your app’s speed. Different hosting packages provide different features.

Consider either cloud hosting, a virtual private server (VPS), or dedicated hosting. Cloud hosting platforms can be flexible, scalable, reliable, and efficient. With cloud hosting, your hardware is virtual. This is cost-efficient, as you don’t need to pay for a real server.

Eliminate the N+1 query problem

One of the most frequent causes of slow app performance is the N+1 query problem faced by most Ruby on Rails applications. This refers to instances in which one line of code results in many more queries than expected. As a project grows, this problem only compounds. You may find that your project is running lots of queries to achieve one result rather than running one query with many results. Let’s find out how to fix slow code in Ruby.

To ensure the performance optimization of a Ruby on Rails application, you need to cut the number of independent database queries. Now you’re probably wondering how to do that. The answer is to eager-load associated relations. That means you should collect related data with one query. It’s important that developers understand this performance issue and are aware of newly introduced queries that can be optimized.

Use pluck

Pluck is a shortcut that helps you choose one or several attributes without needing to load the corresponding records. Let’s compare pluck with map. Map loads objects into memory and gets an attribute. Pluck returns an attribute without loading objects into memory. With pluck, you get better SQL performance and less time and memory use by Ruby on Rails.

Caching

This is a big topic, as there are many types of caching that can be applied in different cases. But in general, caching helps you store content generated during the request–response cycle and reuse it when responding to similar requests.

Gems and plugins are your friends

How to optimize code of Ruby on Rails apps? A common way to speed up the development of a web application with Ruby on Rails as well as the app itself is using gems and plugins. But gems and plugins can speed up your app only if you don’t use too many of them. We’ve already mentioned that using the Bullet gem solves the N+1 problem that most Ruby on Rails applications face. But there are other useful gems and plugins that can help you optimize RoR code.

Why Ruby on Rails?

Rails have some very well-developed features that make it popular with the developer, some of them are ...

Convention over configuration

It helps to create the corresponding advanced components by automatically sensing simple conventional elements.

Automated Testing

RoR runs its own set of tests on the code you write. You can save time and effort in quality assurance.

Scaffolding

This feature allows the programmer to define how the application database should function. After that, the framework automatically generates the required code according to it. The scaffolding technique creates interfaces automatically.

Libraries

RoR has a lot of vast libraries to equip a developer with all the necessary tools to produce high-quality product AJAX library, Database access library, and Common tasks library are some of the few that RoR comprises in its collection.

Ruby on Rails is intended to emphasize
  • Convention over Configuration (CoC),
  • Don't Repeat Yourself (DRY) principle.

    • Convention over Configuration means a developer only needs to specify unconventional aspects of the application. For example, if there is a class Sale in the model, the corresponding table in the database is called sales by default. It is only if one deviates from this convention, such as calling the table "products sold", that the developer needs to write code regarding these names. Generally, Ruby on Rails conventions lead to less code and less repetition.

    Don't repeat yourself means that information is located in a single, unambiguous place. For example, using the ActiveRecord module of Rails, the developer does not need to specify database column names in class definitions. Instead, Ruby on Rails can retrieve this information from the database based on the class name.

    Fat models, skinny controllers which means that most of the application logic should be placed within the model while leaving the controller as light as possible.

    Many high-profile consumer web firms are using Ruby on Rails to build scalable web applications. Some of the largest sites running Ruby on Rails include Airbnb, Cookpad, GitHub, Scribd, Shopify, and Basecamp. As of January 2016, it is estimated that more than 1.2 million web sites are running Ruby on Rails.

    Ruby on Rails includes tools that make common development tasks easier "out-of-the-box", such as scaffolding that can automatically construct some of the models and views needed for a basic website. Also included are WEBrick, a simple Ruby web server that is distributed with Ruby, and Rake, a build system, distributed as a gem. Together with Ruby on Rails, these tools provide a basic development environment.
