Bufferbloat Test
Network Performance Analysis with Real-time Visualizations
Comprehensive network testing with baseline, download, upload, and loaded latency measurements
Server Location
Summary
Latency Analysis
Response time throughout the test. Lower values indicate a more responsive connection.
Throughput Over Time
Download and upload speeds measured throughout the test.
Understanding Your Results
Bufferbloat occurs when network equipment buffers too much data, causing high latency during periods of high throughput. This creates lag in real-time applications like video calls and gaming.
Test Phases
- Baseline: Measures your connection's idle latency (the best-case scenario)
- Download: Measures latency while downloading at maximum speed
- Upload: Measures latency while uploading at maximum speed
Grading Scale
- A+: <15ms increase - Excellent
- A: 15-50ms increase - Very Good
- B: 50-100ms increase - Good
- C: 100-300ms increase - Acceptable
- D: 300-500ms increase - Poor
- F: >500ms increase - Very Poor
