When it comes to network management, there are two challenges that are ever-present; ensuring optimal network performance and maintaining uninterrupted network connectivity. Network admins are the unsung heroes, diligently managing the digital highways that connect the modern world. To maintain the delicate balance between seamless user experience and network reliability, two crucial practices come to the forefront: Network Load Testing and Load Balancing.

You write code. Open a PR. CI runs. PR merges. Prod’s on fire by 5pm. Maybe you skipped writing some tests. (It's tedious, sometimes unclear, and easy to ignore when you're racing to ship—until something breaks and you realize a test could’ve saved your Friday night.) Maybe the PR review was more of a drive-by from a teammate who barely had time to skim the diff. But reviews and tests matter.

All applications need some form of testing, whether frontend, backend, stress testing, or any other. Playwright can help. Playwright is an end-to-end testing framework for web applications, supporting cross-browser testing (Chromium, Firefox, WebKit) from a single API. Its built-in test runner (Playwright Test) provides hook functions to manage set-up and tear-down logic around your tests.

We ran real-world load tests across seven different infrastructure plans—from Grid to Dedicated Split—using realistic conversion rates, bot traffic blends, and ERP-driven API imports. The findings were clear: performance scales predictably with resources, but only if your code, cache, and configuration keep up. This blog post walks through key results, why API load is disproportionately expensive, and what metrics matter most. How well does Shopware actually perform under load?

This guide aims to help your team shift testing left, simulate real user behavior, and catch critical issues early as part of CI/CD, prevent regressions from reaching production by automating tests as part of your CI/CD and aborting deployments that contain issues. Synthetic monitoring is a great way to check important flows in production and make sure everything is working the way it’s supposed to.
