网速测试.
测量您的网速：延迟、抖动以及下载和上传速度（Mbps），配有动态测速仪表和实时曲线。
点击 GO，测量到最近的 Cloudflare 服务器的延迟、抖动、下载和上传速度。 关闭其他下载和视频通话，可获得更准确的结果。
测试数据会与 Cloudflare 的公共测速服务器（speed.cloudflare.com）交换，与访问任何网站一样，对方可以看到您的 IP 地址。PasteZap 不保存您的测试结果。
结果受 Wi-Fi、其他设备和应用、浏览器以及到 Cloudflare 的线路影响，可能与您的套餐或其他测速结果不同。在高速网络上，一次测试可能消耗数百 MB 流量。

英语技术说明
Uses Cloudflare’s public speed test servers (speed.cloudflare.com); random test data and your IP address reach Cloudflare, nothing is stored by PasteZap. About 10 seconds per direction with up to 4 parallel streams; caps of 300 MB download and 150 MB upload per test. Results depend on Wi-Fi, other traffic, the browser and the route to Cloudflare, and can differ from your plan or other speed tests.
Ping is the median of 20 time-to-first-byte samples minus the server processing time that Cloudflare reports; jitter is the mean difference between consecutive samples. Throughput is measured with growing request sizes and parallel connections, excluding the warm-up period. Upload speed counts only requests the server has fully received, because browser upload-progress events report locally buffered bytes and overstate speed.
A fibre line might show ping 12 ms, jitter 2 ms, download 480 Mbps and upload 210 Mbps; on mobile data the test can use several hundred megabytes.
