Internet 速度 testの使い方

何を計算するか、いつ使うか

Measures the download 速度、upload 速度, latency、whether your broadband or mobile data your connection from your browser, using Cloudflare’s public speed servers. It gives a quick check jitterはperforming as expected.です

使い方の手順

  1. 閉じる other downloads、streams、cloud backups.
  2. Press “開始 test”.
  3. Wait while latency、download、upload are measured, about 15〜40 seconds.
  4. Read the 結果,またはpress “Test again”.

各入力項目の意味

  • 開始 test – Begins the measurement. Thereはなし〜enter.です

結果の読み方

  • Download – megabits 単位 second (Mbps).のHow fast データ arrives,
  • Upload – Mbps.のHow fast your device 缶 send データ,
  • Latency (ping) – The 最短 round-trip 時刻〜ミリ秒.のthe server,
  • Jitter – ミリ秒.のHow much latency varies between 測定単位,

計算式

5 Mbps = bytes × 8 ÷ seconds ÷ 1,000,000. The test downloads filesの速度、10、15 MBと1 uploads files、2、3 MB、とreports the best run. Latency is the lowest of eight small requests,、jitterはthe average difference between consecutive latencies.です

計算例

1.2 secondsのDownloading 15 MBは15 × 8 ÷ 1.2 = 100 Mbps.です

前提と限界

  • データ, which matters on a mobile データ plan. The test uses roughly 35 MB
  • Results are〜one server near youと缶 differ 開始 other 速度 tests.
  • Browser、Wi-Fi quality、other devices on your ネットワーク all affect the 結果.

よくある間違い

  • Testing over Wi-Fi 開始 a far 部屋とblaming the provider.
  • Leaving video callsまたはdownloads running during the test.
  • Mixing up megabits (Mbps) with megabytes. Divide by 8〜付与 megabytes 単位 second.

よくある質問

Whatはa good internet 速度?です

For one person、25 Mbpsはenoughです個でHD streaming、video calls. Households with several users usually want 100 Mbpsまたはmore.

Whyはmy 速度 lower than my plan?です

Plans quote the best case on the line. Wi-Fi、day other devices, the time、the test server all reduce 結果.

Whatはjitter?です

latency. High jitter makes callsのVariationとgames stutter even when speedはhigh.です

How much データ does the test use?

About 35 MB.

Why did the test fail?

An ad blocker、firewallまたはlost connection can block the test servers. Turn the blocker引き個でthis page、try again.
