Smart People tend to make smart choices. And choosing Ruby on Rails development platform for your Application is definitely a smart move. Ruby on Rails development tool is extremely popular as it extensively speeds up the development process.

This framework provides developers with a great collection of libraries increasing work efficiency and effectiveness.

However “it’s still not enough”, just choosing ruby on rails does not mean that your application is going to be smooth and flawless. Well, it’s highly and likely possible that a user may never pay a visit to your application if your app is taking more than 2 seconds to load. Users expect the app to load as quickly as possible, and it is our duty to meet their expectations.

Speed really matters. The performance of an application is crucial, as it plays an important role in making your application successful. Poor performance can decrease an app’s ratings. So if you are looking for a way to Speed Up Your Ruby on Rails App, then here are the best tips that might surely be a lifesaver for you.

It’s time to change your web hosting services

Test your application thoroughly and if your application is facing issues in services like server management, backups, etc. Then it’s time for you look for another web hosting service provider, a web host can influence the speed of any application. It might be doing the same to your Rails on rails application.

Reduce the size of your media

If we break down the storage consumed by the different components of our application then media including images and videos would easily be the first. You can tremendously improve your application speed just by removing or chipping of your media size. But that doesn’t mean you have to compromise with the quality. Look for images can be shrunk without loss of meaning or quality.

Add Index to Your Database

Applications tend to slow down and even crash when they receive more traffic. This happens due to the extensive expansion of databases. I mean its more difficult to look for a topic in a book without a content page or a bookmarker. Index are quite similar they make lookups easy by reducing the range of search for a keyword. Without indexes, the database engine will check every record in the table until it finds a match.

Carefully use Plug-ins and gems

Using Plug-ins and gems while building your app can easily speed up the process and also help solve many problems. APIs, Security, Active Record, testing, debugging, deployment, authentication, etc are few of the complex and crucial tasks that can be taken care of within handful of minutes by using plug-ins and gems. But you wouldn’t want to overload your application with plugins and gems as it could backfire and make your application bulky and slow.

Get Rid of N+1 Query

One of the major reasons application developed using Ruby on Rails development platform shows slow performance is due to the N+1 query. Speaking in simple terms it refers to instances in which one line of code results in many more queries than expected. The problem compounds as the code gets larger.
It is important that developers are aware of this problem and its simple solutions such as :

1. Cut down on the number of independent database queries.
2. Using the Bullet gem. Etc.
3. Eager loading.

Reduce Garbage Collector Call Amounts

A fun fact for our readers, every time the garbage collector launches, the implementation of your main code is suspended for 100-400 Mili seconds. So you might wanna take a closer look at your code to avoid this issue in future. Carefully use methods which duplicate the array specified as the input parameter such as ‘reject’ and ‘reject!’ methods and understand how ruby classes and libraries works.

Avoid Dynamism

Although find_by and find_all_by dynamic methods are really cool, they are also kind of slow because each one needs to run through method_missing and parse the filename against the list of columns in the database table.

Select the Right Session Storage

While writing the code, it is very important to understand where the data packets were received after client interaction with the server. These are one of the best and most recommended external cache storage the DRb Store, in the MemCache Store, Redis storage or in the ActiveRecord Store. You can opt for any of these depending on your requirement.

Use CDN

Just imagine about an interconnected system of computers on the Internet that provides web content quickly to different users by duplicating the content on multiple servers and directing it. Well yeah, we do have such a system called content delivery network. It improves your application performance in case concurrent users are working on it.
