Common Application Performance Bottlenecks—And How to Avoid Them?

Common Application Performance Bottlenecks—And How to Avoid Them?

In computing, the term “bottleneck” refers to an overloaded network, a device whose one component is unable to keep pace with the rest of the system, thus slowing overall performance, or an application issue that may be causing your customers/end-users to wait indefinitely while performing business critical operations. 

Fixing bottleneck issues usually results in returning the system to a stable level of performance; however, to fix bottleneck issues, it is necessary to first identify where the issue lies which decides the all-important metric(s) – mean time to detect (MTTD) & mean time to resolve (MTTR). 

Poor application performance can be caused by a variety of factors. Even just a few seconds of application downtime can have an adverse effect on revenues, reputation, and customer satisfaction. Understanding and overcoming barriers to optimal application performance is crucial to delivering the best experience to each user.

Best Practices for API Testing

Best Practices for API Testing

Introduction​

APIs are the “middle man” between the layers and systems in an application or software.  API (application programming interface) testing occurs at the message layer without GUI. During integration testing, it is determined whether the APIs meet the testers’ expectations regarding functionality, reliability, performance, and security. When faults occur, they are costly, both in terms of the direct costs of resolving the defects and in terms of the indirect costs of damaged relationships, lost business, and missed development time. Inadequate software testing raises the risk of developer issues, stakeholder displeasure, and poor customer experiences. API tests are the quickest ways to check the functionality, reliability, performance, and security of the programming interfaces. An API is a software middleman that allows two programs to communicate with each other or the “middleman” of the layers and systems of an application or software. An application programming interface (API) is the interface that allows various software to communicate with one another.

How to run JMeter test in NetStorm

Analyze-the-Test-Result
You can execute JMeter tests in addition to other NetStom scripts. A scenario contains a JMeter script executed in NetStorm for performance testing. The results from the JMeter script are collected and displayed in NetStorm and further available for investigation in Analysis.
The best part is that all of this is done in a very easy manner without any limitations & restrictions. This blog post shows how to run JMeter scripts from NetStorm.

Key Features of NS

A user can run multiple scripts at a single time.

A user can pass additional parameters to JMeter from NetStorm

We can use distributed mode to run tests from multiple locations.

Taking Performance Testing to the Next Level!

Taking Performance Testing to the Next Level!

Performance testing is an essential activity while delivering critical software applications. Be it an e-commerce web application or a mobile app, identifying and determining the behavior of the traffic that is going to hit is the major concern. In view of past patterns and future outcomes, we need to understand, evaluate, and break down the level of activity that we need to perform to serve them without any deficiency. In addition, we should prepare to handle the situation gracefully if it reaches the peak load.

Do you know – A single generator can create more than 3 million virtual users for load testing?

In other words, Do you know – A single generator can free you up of operational nightmares (costs, other operational overheads) of managing multiple generators in your performance testing infrastructure.

Today, hundreds of thousands of users hit a website on a daily basis. During peak sales it crosses million/s. Expect your web application to slow down a bit if not becoming unresponsive.

Do You Know – The importance of having production-like environment for truthful load testing?

Performance testing is a complex activity where dozens of factors contribute to its success. The effective use of all these factors is necessary to get repeatable and consistent performance test results.

Recreating a production-like scenario is an essential part of the whole testing activity because minutest of the differences can completely invalidate the test results.
