Developing with performance in mind

Making applications work is the responsibility of many developers. What we often forget though when building new systems are the non-functional aspects such as performance and reliability. In this post, I’ll focus on developing with performance in mind, which is already the credo of the best software engineers.

Performance has a significant impact on revenue

Users naturally want applications that respond quickly, and recent research shows that 25 percent of users stop using websites if load times take 4 seconds or longer. For a company with a revenue of 1M, such a slowdown means losing $250.000 each year.

It all boils down to the programming languagesthe basis of our human-to-machine interaction—that developers use to code. This source-code as it’s known, is used to write algorithms that solve given problems. Complex applications can actually contain several million lines of code. Finding solutions for the given problems can be a case of trial and error. The design patterns released by the software engineering industry, go a long way in addressing many of these problemshelping us to implement the best solution. As yet, however, no design patterns address performance issues.

If you are among the many who tend to neglect this all-important aspect of performance, you’ll keep running into similar problems as a result. You’ll find that applications are hanging and that loading is slow; not to mention the reliability issues that keep cropping upall due to a lack of knowledge in coding for performance.

To fill this gap, Performetriks is providing the unique training course ‘Developing with Performance in Mind’. The training, which consists of about 100 coding sessions, guides engineers on how to code for high-performance applications. Additionally, attendees learn some highly valuable do’s and don’ts to add to their best practices.

Who should attend this training?

The training will hugely benefit engineers with software-development experience in any programming language. The typical mix of people attending our tutorials includes:

  • developers
  • architects
  • test and performance engineers

The screenshot below highlights the way we guide participants through the training. We share our experience on how small mistakes can result in massive performance slowdowns. We also show good and bad coding practices, execute both statements, measure response times, and present the processing time to the trainee.

Frontend development for performance

Developing modern web applications can be a massive frontend programming challenge. Our training provides over 20 best practices for achieving the optimal frontend performance anti-patterns.

Backend development for performance

Fast and reliable services are now an essential prerequisite to providing an excellent user experience. From a performance perspective, many pitfalls await the developers who are implementing backend services. The way data structures are handled, for example, is among the many challenges that can have a massive impact on response times. Our training provides developers with some excellent insights into backend coding-related performance issues, and so the developers learn how to avoid these issuesresulting in top performance.

General coding for performance advice

Algorithms are at the core of our business applications. When developers are focusing on making the application work, they gradually fall into coding pitfalls. The errors that result then lead to massive performance slowdowns. Our training helps to build awareness on how to avoid these classic coding for performance mistakes.

Testing for performance

Coding for performance helps developers avoid the common anti-patterns and improves the software quality. When your testing team executes the test cases, they can’t actually predict how your application will behave when it hits the real production volumes. Running load and performance testing will allow you to simulate thousands of concurrent users on your new application and verify that performance extends to the boundaries as required.

Monitoring for performance

Following the deployment of the new application on production, you need to be proactive. You need to understand the end-to-end performance as well as the availability of your most important business cases. Continuous performance monitoring on production allows you to mimic real user actions. If performance or availability still falls short of your requirements, a notification will be sent to your preferred communication channel, alerting your teams so they can fix those issues before your customers are impacted.

Summary

Building responsive and reliable applications involves these 4 areas:

  • setting the performance requirements
  • coding for performance
  • testing for performance
  • monitoring for performance
