Physical CPU and Logical CPU

To understand the difference between Physical and Logical CPU (core), you need to run the command lscpu on your Linux machine and you will get a result like this: Now, we will focus only on some important attributes, rest are not so much important with respect to this topic, so I will park them as of now.…

Performance Counters of tiers

Performance Metrics of Tiers

The previous post explained about the software architecture and its types. Since each tier has different roles and operations hence the performance matrices are also different. Below is a list of certain mandatory performance metrics for each of the tiers which should be monitored during the performance test. Client Tier Since there is a need for better application performance…

Software Architecture and its types

Software Architecture is a system to represent the collection of components that accomplish a specific function or set of functions. There may be one or multiple components in the foundation of an architecture on which software can be built. A software architecture helps to define and represent the component(s) and their relationship. We can understand…

Performance Testing vs Performance Engineering

Performance Testing vs Performance Engineering

Software Performance Testing and Software Performance Engineering are the two different sides of the same coin. Similarly, the roles and responsibilities of a performance engineer are different from a performance tester. Hence PTLC and PELC are defined to streamline the activities of Performance Testing and Performance Engineering respectively. Let’s try to understand the difference between Performance Testing and Performance Engineering…

Performance Engineering Overview

What is Performance Engineering?

Software Performance Engineering is the systematic approach of constructing the software that meets the performance objectives. It is more related to build a tuned software application at the early stage of the software development life cycle whose performance satisfies all the non-functional requirement during performance testing phase. On the other hand, Software Performance Testing is the act of evaluating the software system for…
