4 minutes readMCP servers have quietly become production infrastructure. If you have shipped a Model Context Protocol server so that Claude, an agent, or a connector can call your tools, that endpoint is now on the critical path. When it goes down, or starts returning errors, your users feel it the same way they would feel any… Read more »
5 minutes readPerformance rarely breaks on the day you run a load test. It breaks three deploys later, on a Tuesday, when nobody is looking. LoadFocus can now run your load tests for you on a recurring schedule, and email you only when a run actually starts failing. Set it once, and let it watch your app…. Read more »
3 minutes readWriting a load test script from scratch is the boring part. You already have the request you want to hammer: it is sitting in your browser’s network tab, in a Postman collection, or described in an OpenAPI spec. So why retype it as a k6 script or build a JMeter test plan by hand? Now… Read more »
5 minutes readk6 is free and open source, and on your laptop it is a joy to use. The moment you need real scale, though, things change: tens of thousands of virtual users, traffic from several regions at once, and results you can actually read afterwards. That is the point where teams discover that “k6 is free”… Read more »
7 minutes readk6 and Apache JMeter are two of the most widely used open source load testing tools, and teams evaluating one almost always end up comparing it to the other. They solve the same problem, simulating traffic against your APIs and websites to find where performance breaks, but they come from different eras and design philosophies,… Read more »
7 minutes readVirtual users (VUs) are the simulated humans that hit your system during a load test. They’re the load. Where real users come from browsers and apps, VUs come from a test harness. JMeter threads, k6 worker goroutines, Locust greenlets. Each VU sends requests, waits for responses, sometimes pauses (“think time”), and repeats. Aggregate enough VUs… Read more »
7 minutes readLoad testing and stress testing are not the same thing, even though the terms get thrown around interchangeably in standups, RFPs, and vendor pages. Both put traffic against your service, but they answer different questions. Confusing them costs you either money (over-scoping a test) or a 3 a.m. incident (under-scoping one). This is the short… Read more »
