Case Study: Criteo enhances performance and scalability with Gatling Enterprise

How an adtech company used Gatling Enterprise to enhance performance infrastructure

Criteo, a global adtech company, needed to replicate its massive global traffic load to ensure its hosting infrastructure could handle growth and maintain performance. To meet this challenge, they turned to Gatling and implemented the self-hosted Gatling Enterprise solution for enhanced performance load testing.

Using Gatling Enterprise, Criteo established a distributed testing environment to accurately simulate traffic, allowing them to perform regular capacity and API testing. The results were significant: the company can now handle over 4 million HTTP requests per second during peak times with response times under 10ms. Gatling enabled Criteo to expand its load testing from 1 to over 10 projects, ensuring a high-performance tech stack that reliably serves 250 billion HTTP requests daily.
