What the numbers mean
Eight signals. One honest answer.
YohFast measures your connection against this test server. Results can vary by Wi-Fi quality, network congestion, device and distance. It never labels a connection as fibre or mobile unless the browser can prove it or you confirm it.
Ping
The round-trip response time. Lower is better, especially for calls and gaming.
Jitter
How much latency changes between requests. Stable connections have low jitter.
Download
How quickly data reaches you. This drives streaming, browsing and downloads.
Upload
How quickly you send data. Important for calls, backups and sharing large files.
Loaded latency
Ping measured again while downloading and uploading. This exposes lag that only appears when the line is busy.
Bufferbloat
The extra delay created by traffic. Low bufferbloat keeps gaming and calls responsive during large transfers.
Consistency
How steadily the connection holds its speed during the test. A high score means fewer sudden dips.
Package delivery
Your measured speed compared with the package speed you entered, giving you evidence for an ISP support query.
