Case Study: InPost keeps parcel delivery fast and reliable with Gatling Enterprise Edition

How InPost keeps parcel delivery fast and reliable with Gatling Enterprise Edition

InPost, a leading European parcel delivery network, faced a significant challenge in scaling its digital platform to handle rapid growth and billions of inter-service calls. Business leadership required proof that the system could manage anticipated surges while meeting strict internal performance standards for latency and success rates. Before choosing Gatling Enterprise Edition, the company struggled with scaling its performance testing infrastructure, which involved manual tuning and fragmented visibility from other tools.

To solve this, InPost implemented Gatling Enterprise Edition for its visualization, scalability, and extensive protocol coverage. The solution provided autoscaled Kubernetes load generators and deep integrations with their observability stack. This enabled them to run critical validations, like a five-day continuous logistics simulation, which uncovered and resolved bottlenecks from code to hardware. As a result, Gatling helped InPost scale its capacity from 1.6 million to over 10 million parcels per day, saving full-time equivalent (FTE) efforts by eliminating manual infrastructure maintenance.
