LibreQoS Launches Next‑Gen Bufferbloat Test
LibreQoS today announced a faster, clearer way to measure internet quality under real‑world load. The new
Bufferbloat Test runs entirely in your browser from the Cloudflare edge, showing how latency, jitter, and
loss change when your connection is busy — the signal that most directly impacts gaming, video calls, and
responsiveness.
What It Measures
- Latency under load: how much delay (“bufferbloat”) appears during downloads/uploads.
- Jitter and loss: stability of your connection minute‑to‑minute.
- Throughput: sustained download and upload rates.
- Fairness: optional “Virtual Household” mode simulates four family members (gamer, calls, streaming, updates) to reveal who’s impacted most.
Why It Matters
- Bufferbloat turns a “fast” connection into a laggy one during activity.
- ISPs and home users can quickly confirm if shaping/queueing is tuned well (e.g., CAKE/fq_codel).
- Runs globally at the edge — no install, no plugins, just a browser.
How To Access
- Standard Test: https://bufferbloat.libreqos.com/
- Virtual Household: https://bufferbloat.libreqos.com/vh/
- Works on desktop and mobile; for the most consistent result, use a wired connection and pause large
background transfers.
How To Read The Results
- Grades (A–F): quick quality indicator based on latency under load.
- Box plot: shows latency distribution; the “Increase” is loaded p95 minus baseline median — the smaller, the
better. - Throughput tiles: show typical sustained download/upload rates.
- Virtual Household tiles: live sparkline, jitter, and loss for each role; the “Most impacted” pill highlights
who suffers under load.
Share & Compare
- One‑click “Share Results” downloads a PNG you can send to support or your ISP.
- ISPs can use aggregate scores to validate QoE improvements across regions and plans.
Privacy
- No login required. The test runs in your browser and collects only minimal diagnostics needed to calculate
results. See our site’s Privacy Notice for details.
