We have already discussed why we love Ruby on Rails and why we prefer as well as suggest Ruby on Rails framework to develop web applications to our clients. RoR framework emphasis on certain principles like don’t repeat yourself and convention over configuration, but remember nothing comes without paying the price for it.
At the time of development, we often take decisions which seem vital at the time, but later on, such choices prove to be decisive to bring application’s performance down. Choosing RoR as your development partner won’t mean your project will succeed, proper care and attention are indeed required to run it efficiently. Performance matters as the performance of an application is a focal point in making your web application successful. So, let’s talk about the easiest ways to improve the performance of your application to make your app faster and often overlooked.
Tips to Improve your Ruby on Rails App Performance
It requires careful consideration to keep your code clean and organized while developing large Rails apps and that too following deadlines. Refactoring in TDD is a time consuming and painful process. However, there are a lot of gems out there to ease the work. So, before taking any single step to boost up your app’s performance, it is advisable to set up a profiling tool like rack-mini-profiler, new relic, scout or RubyProf. The profiling tool is safe to run in the production mode, as it will identify the slow code and critical bottlenecks that concern your application.
- You website host matters – so give it special consideration
- N+1 query needs resolution
- Add indexes to your database
- Make use of Gems and Plugins
- Turn Caching on whenever possible
If your RoR application is tested by all sorts of speed analysers. Even in a development environment, it flies, but after the launch of the project, the user feedback states that page loading is taking longer than usual. How could it be different?
My recommendation is to change the web hosting provider. Try to employ the services of CDN – Content Delivery Network, a geographically distributed network with a 100% guaranteed delivery of data packets with a minimum amount of hops. To take control over your RoR deployment choose Google Cloud Platform or AWS are reliable and scalable solutions. Heroku is also a sound option to launch your application faster. If you need a high level of control, Digital Ocean is offering bundles called droplets to run production applications.
One of the frequent reasons for the slow performance of your application is an N+1 query. The bullet is one of the Ruby gems that is strongly recommended to improve your performance. When your application gets bigger, your app may try to run numbers of queries to achieve a favourable result, instead of collecting related data with one query. Identifying N+1 problems is quite challenging as you will only detect these database performance issues when moving to a production-sized database. Bullet gem is highly recommended to identify N+1 queries.
To fix the traffic issue add indexes to your database. Lack of indexes on columns is the reason why some queries are taking so long to execute than they should. Without indexes, the database engines require manual checking of every record until it finds a match. However, indexes do this job a lot faster to focus on choosing the solution.
Among the numbers of listed ways to speed up your RoR application, acquaint yourself with gems and plugins. The growing RoR community has fantastic Rails plugins out there to save a lot of your time. Still, it is advisable to do some research on the source before using a plugin for your intended purpose. There are useful enough gems and plugins to optimise your RoR code.
If the previous recommendations didn’t work in your case and looking for a better speed than execution, simply turn on rails caching. Assets, fragments, cache pages, SQL request, actions – select whatever you need in your case to improve your rails performance. The official Rails guide is offering in-detail technical details on caching APIs of Rails. By caching the data with the active record, you can directly store the user requests in memory without connecting it to a database management system. Rails cache optimise manipulations involved in complex requests to the database.
There are numbers of aspects which could cause bottlenecks to your RoR application. Database indexing, reducing heap allocation, and load balancing is some of the significant ways to speed up your rails application. To give your app users a smooth experience, it is advisable to follow the above guidelines to ensure great performance from different geographical regions.
