Discover the Power of Cyrex Swarm

If you haven’t heard about Cyrex Swarm, it’s our proprietary load testing technology. We’ve delivered it to clients like Avalanche Studios, Epic Games, Jagex, and Mythical Games. If you’re familiar with load testing, you might be wondering what makes Swarm so special? There’s plenty of load testing solutions available. However, most are focused on web communication and we found them limited on user tests. With Cyrex Swarm, we are capable of testing scaling up to a million concurrent players.

We’ve integrated with almost every networking library in the gaming industry. So, if you’re using any standard or typical library known in the gaming, we guarantee out-of-the-box support from Cyrex Swarm. It talks to your backend and is not linked to any singular point or piece, when we say Swarm, we mean it. Everywhere it needs to be, as much as it needs to be.

How our testing solution works

Foundation Preparing Solutions

Using these scripts, we test how the system handles high volumes of users operating as users would. As opposed to typical load testing, which is similar to a DDOS, we don’t just flood packets into the system.

Simulation Test & Learn

We simulate each user process fully; from connection and authentication to entering and searching for matches in video games. This process occurs entirely on the network level, connecting directly with the API or network protocol (UDP/TCP).

Solutions Observability of a Secure System

When doing these tests, we are not limited to only the numbers that became a struggle for the system. We will have the ability to hone in on precisely which functionality began to struggle and offer specific solutions to counteract its effect.
