Internet Speed Test

How to test your internet speed

Click “Start test” and wait about 25 seconds. The test measures ping, download and upload speed between your device and the PR-CY server, one after another. No sign-up and nothing to install.

For a more accurate result:

• close downloads, videos and online games in other tabs and apps;
• use a cable if you can: Wi-Fi through a wall noticeably cuts the speed;
• run the test 2–3 times and go by the average.

What the test measures

• Download — how much data you receive per second: opening websites, video, file downloads. The key metric for most tasks.
• Upload — how much data you send per second: video calls, streaming, uploading photos and documents to the cloud.
• Ping — how many milliseconds the server takes to respond. Matters for online games and calls: under 50 ms is great, above 100 ms causes noticeable lag.
• Jitter — how much the ping fluctuates between requests. Lower means a more stable connection: above 30 ms audio in calls starts breaking up.

What speed you need

Why the speed is lower than your plan

Providers state the maximum speed to their own equipment. The real result depends on your Wi-Fi router, network load at peak hours, other devices at home and the distance to the server. If your wired speed is consistently more than 20–30 % below the plan, save the results of several tests and contact your provider.

How the test works

The test opens several parallel connections and downloads, then uploads random data for 10 seconds each. The first seconds are not counted, because the connection is still ramping up. No data is stored.
