Internet Speed Test

Measures your actual download speed, upload speed, and ping — not the theoretical maximum. Run it a few times at different times of day for a realistic picture.

How it works

Ping & Jitter — 1 warmup + 10 HEAD requests to your server. Drops 2 slowest, averages the rest. Jitter = mean deviation between consecutive samples.

Download — 4 MB TCP warmup + two passes of 6 parallel streams from Cloudflare (150 MB each). TTFB excluded. Both passes averaged.

Upload — Two passes of 6 parallel streams posted directly to Cloudflare (60 MB each). Uses text/plain Blob to avoid CORS preflight. Both passes averaged.

Results may vary from ISP-provided tests due to server proximity and network conditions.

How to get an accurate speed test

One test gives you a number. Three tests at different times of day give you the truth.

01
Close other tabs and apps first
Anything downloading or streaming in the background will eat into your measured speed. Close what you can for a cleaner result.
02
Click Start Test
The test runs download, upload, and ping in sequence. Takes about 20–30 seconds total.
03
Run it a few times
One test can be skewed by a momentary blip. Run it 3 times — morning, afternoon, evening — and average the results. That's what you're actually getting.

It downloads and uploads chunks of data to test servers and measures how fast the transfers complete. Ping is measured by timing a round-trip request to the server.

A few reasons: Wi-Fi is almost always slower than a wired connection. Your router, the number of devices on your network, and congestion on your ISP's network all affect real-world speeds. The advertised speed is a theoretical maximum under ideal conditions.

Under 30ms is excellent. 30–60ms is fine for most games. Above 100ms you'll start noticing lag in fast-paced games.

Zoom and Google Meet need about 3 Mbps for HD video. 4K streaming on Netflix needs 25 Mbps. If you're doing both at once, add them up.

Test both if you can. The difference tells you how much your Wi-Fi setup is costing you. A wired connection to the same router is almost always faster.

Yes. On mobile it tests your cellular or Wi-Fi connection, whichever your phone is using.
