The Performance Engineering Blog

Introduction This series of articles will introduce the reader to explore more about Performance Engineering, specifically how to deal with actual issues of the product in a production deployment scenario.   This is the most discussed area and most of the people I have interacted with look forward to getting in to this role and deal with actual issues and make their contribution.   This work requires knowledge and understanding from a multitude of aspects like –        The product design         Usage profile of the product         CPU and Memory and Disk configuration of the platform         Software configuration – Memory settings         Connected software components and their impact The reader is expected to look at the problem holistically to make the best use of the resources being deployed and then tune the application to obtain the required performance.   As t...

Introduction This series of articles will introduce the reader to the arena of Performance Engineering.   After my first two blog articles which provided a 35000 feet of what is Performance Engineering is all about, I am sure most of you would be intrigued to understand more about it.   This series of articles should help you get started (in case you would want to take a dive) or would act as a refresher to many who are already in to this domain.   This series aims to discuss the testing aspect of Performance Engineering, how it is done, why it is done and what are the key take away points. Let’s race away by trying to answer the relevant questions What is a load test and why is it needed? After the advent of the internet and specifically the dotcom revolution bought the entire world close to being online.   Applications which were erstwhile desktop started getting connected via the internet.   With extensive development and advancements in the connection te...

  Introduction Performance engineering (erstwhile Performance Tests, Load tests) and Site Reliability Engineering are the two most commonly interchangeable terms currently being used in the current software industry.  Although the gap between them is quite narrowed down but if looked at a microscopic level, these two are totally different fields in their own sense. Let’s try to look at each one of them in some detail today in this blog.   This will be an extension to my previous blog post and might sound repetitive a bit from a Performance Engineering standpoint, but for keeping this post complete, some of the information is reused here.   Performance Engineering From the dotcom revolution in the early 2000’s the requirement to ‘test’ websites became a need of the hour and lot of dedicated commercial / proprietary tools took the world by storm.  There was a time when the terms Load Runner / Silk Performer were synonymous to Load tests.  Due to the presence ...

  Introduction This post will help you understand what performance engineering is all about, its basics is and how it goes about in the industry. Let’s get started! This is how Wikipedia defines performance engineering Performance engineering  encompasses the techniques applied during a  systems development life cycle  to ensure the  non-functional requirements  for performance (such as  throughput ,  latency , or  memory  usage) will be met. It may be alternatively referred to as  systems performance engineering  within  systems engineering , and  software performance engineering  or  application performance engineering  within  software engineering . The Basics We all in the IT / Computer Engineering / Software industry have seen how the applications evolved over the years and the way in which their usage has changed. The first phase of evolution of an application after development is ‘Test...
