Soak Test – A Practical Example

Jmeter Feb 21, 2019

A look at how we can build a complex soak test using BeanShell Samplers.

As performance testers Soak Testing is a test that is often overlooked. We always think of Peak Volume tests and we always like to push the system to its limits in the form of a Scalability Test but often the Soak Test is forgotten about. It’s a great test and it tells you many critical aspects about your application under load, things that no other test can and is critical in determining if you application is fit for production.

OctoPerf 10 is out

Innovation Feb 12, 2019

New logo, templates, remote control your virtual users and a lot of new cool integrations to start the year off right with OctoPerf 10.

It has been a few months since the last update post and as you will see we have been quite busy. Let’s not waste any time and look first into the most obvious change of them all.

JMeter Properties: Configurable Test Plans

Jmeter Jan 14, 2019

An in-depth look at the benefits of using JMeter properties to create configurable test plans.

Your company probably runs JMeter test plans on a regular basis. Tests constantly need to be adjusted to change settings like concurrent users or test duration. Editing the JMX is time consuming and error prone. It’s painful, especially if you run test using Continuous Integration as part of a Shift-Left strategy. Thankfully, there is a way! Let me guide you through all the options to design flexible JMeter test plans using configurable properties.

Networking with OctoPerf 9.6

Innovation Nov 27, 2018

A big focus on the network with this new version of OctoPerf with enhanced proxy support and IP spoofing as the key features.

Since our last post about OctoPerf 9.4, we’ve been working on a lot of different subjects. As usual, you can find all the details in our changelog, but let’s have a look at the key improvements. IP Spoofing IP Spoofing is a technique used to impersonate another computing system. In performance testing it is interesting when you face a load-balancer or anti DDOS mechanism that requires each virtual user to have a different IP.

Elasticsearch: Optimization Guide

Development Sep 21, 2018

After using Elasticsearch for several years in production, we’re sharing our hardware and software best practices to squeeze every bit of performance out of your cluster.

You may already have setup an Elasticsearch cluster but you’re struggling with numerous issues: Indexing is slow: somehow you’re not getting the ingestion performance you expected, Out of Memory: your nodes are regularly hitting the Java Xmx mark and you don’t know why, all CPU cores are not used: somehow you are struggling to vertically scale the database to take advantage of multiple CPU cores, and much more. After spending several years maintaining, upgrading and tweaking Elasticsearch, we’ve learnt a lot of things along the way.
