Increasing the transaction levels and user levels can require you to tune your load tests. That may take some detective work. Here’s a real example. The Problem. A RedLine13 customer had an API test that ran for 12 minutes and generated around 500 transactions a second when run locally on their PC. Taking the same test running on Redline with 4 separate machines they expected to generate 2000 transactions but they were generating around 1040 transactions.Read More →

Writing a chat application with popular web applications has traditionally been very hard. It involves polling the server for changes, keeping track of timestamps, and it’s a lot slower than it should be. In this post we’ll walk through how to improve your WebSocket application performance. Sockets have traditionally been the solution around which most realtime chat systems are architected. is a JavaScript library for realtime web applications. It enables realtime, bi-directional communication betweenRead More →


JMeter is an excellent open source load testing tool used by thousands of developers. If you want to scale your tests you have some options. You can do it yourself. Or you can scale out your JMeter test on the cloud with RedLine13. JMeter Load Testing – Do It Yourself Scaling JMeter beyond 500-1000 users increases complexity and setup time. Additionally, JMeter reports are usually displayed at the end of the test and only exist locally. There’sRead More →

One of the most famous catchphrases to come out of the Continuous Integration / Continuous Delivery tsunami sweeping DevOps is “Who broke the build?” We’ve even seen clever shops rigging Jenkins to a ping pong ball gun to fire at the developer who just checked in code that broke the build. Continuous Integration / Continuous Deployment / Continuous Performance RedLine13 is so easy to use and so inexpensive. It is being used on an increasing frequency as partRead More →

When companies are growing fast, their main concern is not scaling. Until it’s an issue.  This is part of maturing devops (development operations). They need, or will need, load testing. Then the questions come up. This blog post should be seen as practical load testing advice, along with the right questions, for any company that is grappling with the need to load test. Load Testing 101 Load testing is based on user requirements. For example, loadRead More →

Easier Load Test Search It’s easy to search your existing RedLine13 tests with new advanced filters. You can already search for your tests by name.

Added Continuous Testing support for CURL and Codeship. This is in addition to existing support for Jenkins.  Continuous Integration (CI) helps automate your code delivery pipeline and enables your teams to collaborate.  Continuous deployment (CD) is the practice of automating the delivery of software to production after passing a series of tests. Which brings us to the need for Continuous Testing. You now have more options for CI/CD Continuous Testing support. We’ve always known that thisRead More →

We sometimes get questions such as “Can I run my Load Test from multiple locations?” The answer is “yes, easily”. It makes sense that testing from one location is not the real world. Therefore, you want to test from multiple locations to simulate the real environment that your site gets, whether that is across your region or across the world. Configure to Run Your Load Test from Multiple Locations So when you configure your test, you simply chooseRead More →

BlazeMeter Comparison

BlazeMeter is one of the leading load testing platforms. RedLine13 has claimed that it provides (Almost) Free Load Testing. This post will first take a look at a BlazeMeter pricing comparison vs. RedLine13. Then it will take a look at a feature comparison because price isn’t everything. In addition, there is the increasing realization by businesses with the value of shift left testing. So this blog post will also look at pricing related to continuous integrationRead More →
