How to implant Performance in your SDLC – Part II

In the previous post, I wrote about why performance is so important and on how to create strong non-functional requirements. Let’s focus a bit more now on the implementation of load and performance tests. This step in the development lifecycle is where the real work for performance-engineering teams begins. You’ve already agreed on the overall process; your non-functional requirements are aligned, and your developer has started on the coding. The performance engineers are now

Rethink performance engineering in the SDLC

Have you ever experienced the frustration of slow-loading applications? Even worse, when one of your business applications is loading slowly, it seems as if you suddenly need to use it a thousand times a day. You hate this application so much because it destroys all your fun at work. If only you knew a way to avoid using that application. The entire brand related to this particular IT service spells only frustration for you. You’ll never use or buy any products related to thi

Rethink performance engineering

We often find ourselves busy with too many things at the same time. Living in this kind of multitasking mode not only affects our health, but also our daily work. It often leads to disaster, in fact. Customers feel frustrated when our new IT services fail to meet their performance expectations. And when you discover that the new application just doesn’t perform well in a real-world situation, you realize how all your investments in building a new product were a waste of money

Better performance in 3 steps

Complex problems often have simple solutions. But when we look at our performance-testing space, many of us dream too much instead of taking action. This blog post introduces you to a few simple ways to achieve better performance. These are easy to implement, but still require a lot of commitment and forward- thinking. And always remember—you can’t improve performance by testing. Test early Neglecting this task is the number-one pitfall. You may have great software designs an

Why you should make performance engineering everyone’s job

A few weeks ago, I saw the following mind-breaking text on one of our popular social media platforms: The bitterness of poor quality remains long after the sweetness of low price disappears. Quality before cost It’s true! Many of us start off by focusing on the price, but regret our decision as soon as problems appear, due to the low quality. This happens to IT services when we cut the cost of implementation to a minimum. On deploying this low-priced service to our end users,

Speed up slow applications

We’ve been developing software for more than 40 years now —so why is the performance of our applications still well below our customers’ expectations? Have we missed something in our software-development pipeline? Agility is very trendy at the moment—but does it solve our quality gaps? Have you ever thought about the entire life cycle of your applications? We develop them within a few months, and often use them for decades. Do you pay enough attention to how easily you can mo

How to close performance-engineering gaps in 2019

There’s more to performance engineering than just load injection and response-time validation. Simulating production volumes on our changed applications—and we have plenty of tools for doing this— makes a good start. But it won’t uncover all your critical performance hotspots. Read this post and find out how to modernize your performance-engineering approach, and close all those remaining gaps this year. Shift performance engineering to the left Unit testing is great for vali

The frustration of slow applications

Performance is not just a part of development—it’s also a component of design. That’s because the user experience and the usability of features both depend so much on response times. It’s surprising how many developers treat software performance as an afterthought, when it’s actually the first priority after an application is ready to run. Optimize early Although performance optimization can mean different things, the value of building performant code is clear. Those project

Performance Test VS Monitoring

With the rise of mobile devices user experience has become more critical than ever before. We have the internet in our pocket, browse through our favorite sites multiple times a day, receive push notifications from our loved ones and buy products online whenever we identify something attractive. This usage pattern is, both, beneficial for those who sell goods online and a challenge for IT service providers. In this post, I will shine a light on how to attract more customer an

Reshaping Business with Speed – Part I

User experience is an all-dominating factor in our digital world. Whether you sell products through web-based platforms or you, use convenient facilities for banking activities, or you get in touch with close friends through social networks, the speed of those IT services influence you massively. A forward-thinking organization has demonstrated that 100 ms load time improvement results in 100 Mio. $ growth in sales. In this post, I will outline why and how speed can push busi

Why do we need Load and Performance Tests

Our expectations for reliable and responsive IT services are increasing, and users are more and more in the driver seat. If applications react slowly to user’s input or are not available, they stop to use those services. Retailer or e-commerce companies are entirely depended on high click rates. Whenever abandon rates go up, it has an adverse impact on their financial revenue. Therefore, successful organizations integrated load and performance tests in their development chain

The Science of Speed

Not so many years ago, organizations tried to fix bad user experience with investments in infrastructure. Hardware provider promised that brand-new CPUs, more RAM, and fast storage would fix the annoying performance hotspots. Obviously, this was just in rare cases a good advice. In this post, I will write about top performance hotspots and how speed is unlocking opportunities across all layers. Top reasons for performance issues Nowadays, the biggest proportion of slowdowns i

Yesterday’s Performance Engineering approach can’t stop today’s Bottlenecks

New technology is popping up almost overnight, and the complexity of our applications is increasing. Virtualization, artificial intelligence, microservices, and machine learning are just the beginning, and there is much more to come. Some people argue that performance is the most important feature. I entirely agree with this statement because slow loading applications disturb the customer’s attention span. Once they mentally left their intended activity due to pure speed, the

The need for Continuous Performance Optimization

Nowadays, information technology is at the heart of every business. Outages or slowdowns in critical software components often impacts the whole organization. According to research from Aberdeen, performance is still an afterthought. A minority of 3 % identify the source of delays, and just 9 % perform root-cause analysis of application problems. Response time measurement is also widely ignored. One in five organizations is collecting response times metrics. It seems that con

There are few things more frustrating than a slow application

Have you ever been affected by a slow loading or not responding application? According to recent studies a typical user is willing to wait up to 4 seconds and will often never return. Obviously, performance is a crucial aspect of our business applications besides their primary objective to work properly. However, many treat it simply as an afterthought. One project I was involved in recently was successfully launching a new account opening form application. In this project, b
