Cultural Tip

In most Spanish‑speaking countries ‘prueba de velocidad’ refers specifically to an internet speed test (e.g., using Speedtest.net). If you’re speaking in a formal context—like a business email—use ‘realice’ or ‘ejecute’ instead of the informal ‘haz’. Also, remember that the word ‘test’ is often borrowed as ‘test’ or ‘test de velocidad’, especially in tech circles.
