Testing One Million eCommerce Orders Per Hour

How fast and well your website can handle serious amounts of simultaneous order intakes can make or break businesses. It depends on your chosen ecommerce platform, of course. So we tested ours.

OK, let's talk numbers. One million eCommerce orders per hour is a nice round number. We tested the Crystallize eCommerce API to see how it handles this ridiculous amount of concurrent orders.

TLDR; we confirmed that our architecture scales and easily handles peak traffic at a rate of 285 orders per second resulting in 1 026 000 orders per hour. That is Black Friday ready 😎

Black Friday ready eCommerce order intake

eCommerce trends show that more brands are doing limited runs and using scarcity to make customers buy their products for a limited period. Typically this is hyped brands like Off-White or the makeup collection of Jeffree Star.

Together with sales like Black Friday, we have seen many webshops being brought down and companies creating online queues as they cannot handle the load. But Black Friday should not mean waiting in line. We shop online not to wait in line, but because it is more efficient and offers a better customer experience.

As a business, you want to ensure that your webshop can handle the load. With that in mind, we decided to check/verify that a Crystallize tenant can tackle peak traffic of 1 million orders per hour (actually 1 026 000). This translates to 285 orders processed per second. Per second 🤯

Shipping 1 million packages is, of course, a different topic, but you can rest assured that your Crystallize eCommerce service can handle the throughput.

Of course, you can sell virtual products like access to a streaming service, in-game purchases, or buying access to a newspaper. In these scenarios, you use the fulfillment pipelines in Crystallize to automatically fulfill the order by using event-driven eCommerce with webhooks.

We used the k6.io load testing service to generate random orders and scaled them to the desired throughput. You can see the results below. On average, each order is placed in 179 milliseconds with a peak concurrent throughput of 285 orders per second.
