点击「开始测试」检测网速
测试大约需要 15 秒
- 1延迟通过向 CDN 服务器发送请求来测量
- 2下载速度通过从多个 CDN 下载文件来测量
- 3一切都在浏览器中运行 — 无需上传数据
注意：结果可能因 CDN 位置和网络条件而异。这是估算值，不如专业测速服务准确。
About Internet Speed Test
Slow internet can disrupt your work, streaming, and gaming. Our free online Internet Speed Test provides a quick and accurate measurement of your current download speed, upload speed, and network latency (ping).
How It Works
The tool works by downloading and uploading small chunks of data from your browser to our servers. It measures the time it takes to transfer these chunks to calculate your bandwidth in Megabits per second (Mbps) and your ping in milliseconds (ms).
Common Use Cases
- Checking if you are getting the internet speeds you pay your ISP for
- Troubleshooting buffering issues while streaming video
- Testing your connection before joining an important video conference
- Comparing the speed of different Wi-Fi networks or mobile data connections
Frequently Asked Questions
It depends on your needs. 25 Mbps is generally sufficient for basic web browsing and HD streaming. For 4K streaming or multiple users, 100 Mbps or higher is recommended.
Speeds can be affected by many factors, including Wi-Fi interference, network congestion, the distance to the test server, and background applications consuming bandwidth on your device.
