Quick answer
How Goroutines and concurrent architecture allow modern engines to execute thousands of 15-second checks flawlessly.
The Heavy Cost of Traditional Runtimes
Building a monitoring engine in traditional, heavily-threaded languages or single-threaded event loops (like Node.js) quickly hits a bottleneck at scale. When you need to execute 10,000 network requests every 15 seconds, memory bloat and context-switching destroy performance.
Enter the Goroutine
We built our core engine in Golang specifically for its concurrency model. Goroutines are incredibly lightweight, taking up kilobytes of memory instead of megabytes. This allows us to spin up tens of thousands of concurrent network requests simultaneously without breaking a sweat.
Speed Without Sacrifice
Because the engine is compiled down to a single binary and utilizes raw TCP sockets, the network overhead is minimal. This architectural choice is exactly what allows us to offer 15-second tracking intervals at a fraction of the hardware cost of legacy systems.
