The Performance Engineering Blog

  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...
