Code Wizards scale checks of Heroic Labs’ Nakama hit 2M CCU — they usually say it may have gone greater

Introduced by Code Wizards

Code Wizards simply introduced it has run, to one of the best of their data, the biggest and most profitable public scale take a look at of a commercially out there backend within the video games trade. The information comes on the heels of the general public launch of scale take a look at outcomes for Nakama working on Heroic Cloud. They examined throughout three workload situations, and hit 2,000,000 concurrently linked customers (CCU) with no points, each time. They might have gone greater, says Martin Thomas, CTO, Code Wizards Group.

“We’re absolutely thrilled with the results. Hitting 2 million CCU without a hitch is a massive milestone, but what’s even more exciting is knowing that we had the capacity to go even further. This isn’t just a technical win — it’s a game-changer for the entire gaming community. Developers can confidently scale their games using Nakama — an off-the-shelf product — opening up new possibilities for their immersive, seamless multiplayer experiences.” Thomas stated.

Nakama on Heroic Cloud was equally examined utilizing AWS working on Amazon EC2, Amazon EKS and Amazon RDS, and matches proper into AWS’s elastic {hardware} scale out mannequin.

Mimicking real-life utilization

To make sure the platform was examined totally, three distinct situations had been utilized, every with growing complexity to in the end mimic actual life utilization below load. The primary situation was designed to show the platform can simply scale to the goal CCU. The second pushed payloads of various sizes all through the ecosystem, reflecting realtime person interplay, with out stress or pressure. And the third replicated person interactions with the metagame options inside the platform itself.  Every situation ran for 4 hours and between every take a look at the database was restored to a whole clear restore with current information, guaranteeing constant and honest take a look at runs.

A better have a look at testing and outcomes

Situation 1: Fundamental stability at scale

Goal

Setup

Consequence

Success establishing the baseline for future situations. High degree output included:

• 2,050,000 employee shoppers efficiently linked
• 683 new accounts per second created – simulating a big scale recreation launch
• 0% error price throughout consumer employees and server processes – together with no authentication errors, and no dropped connections.

Situation 2: Realtime throughput

Goal

Setup

Consequence

One other profitable run, proving the capability to scale with load. It culminated within the following prime line metrics:

• 2,020,000 employee shoppers efficiently linked
• 1.93 Billion messages despatched, at a peak common price of 44,700 messages per second
• 11.33 billion messages acquired, with a peak common price of 270,335 messages per second

Be aware

As could be seen within the graph above, an Artillery metrics recording situation (as seen on GitHub) led to a misplaced information level close to the tip of the ramp up, however didn’t seem to current a problem for the rest of the situation.

Situation 3: Mixed workload

Goal

Setup

Consequence

Altering the payload buildings to database sure made no distinction because the Nakama cluster simply dealt with the construction as anticipated, with very encouraging ninety fifth percentile outcomes:

• As soon as absolutely ramped up, shoppers sustained a top-end workload of twenty-two,300 requests per second, with no vital variation.
• Server requests 95% (0.95p) of processing occasions remained under 26.7ms for the whole situation window, with no surprising spikes at any level.
