Typically there are other devices on the network consuming bandwidth, leading to inconsistent speed test results. Unless this is the cause, run speed tests on several devices to confirm. If problems persist, reach out to your service provider. Streaming should work fine at 200Mbit/s for multiple 4K streams.
Speedtest.net relies on the nearest server to the testing location, which ISPs often control by giving preferential treatment to their own networks—resulting in low latency and fast speeds. This manipulation means test results can be misleading, especially for services like Twitch or Netflix that are throttled. The frontend itself doesn’t alter the underlying network behavior, making it equally ineffective for diagnosing connection problems.
Check the bandwidth beyond your ISP. Run a speed test on another server or in another country.
It would be wiser to determine the country first. Speed tests and data handling vary by location. I’m aware that internet service providers in the U.S. can be quite questionable. It makes sense to pick the nearest server for a speed test, since performance depends on your local network. Anything further is beyond your control. You should aim for the quickest path possible.
Slow increasing speed is typical and usually planned by speedtest.net. It doesn’t indicate anything about your actual connection. Their servers can’t measure your internet speed directly. If they begin sending data at full capacity, your ISP would start discarding packets that exceed limits, causing many resends and making it harder to gauge real speed or prolong the test. They gradually increase the rate until they hit the point where ISP drops packets, then reduce slightly. This helps them accurately find your connection speed. The goal is to measure peak performance, not the ramp-up time itself.
