Preventing ISP manipulation for accurate results
Why Anti-Caching Matters
Some ISPs may implement caching strategies to artificially inflate speed test results. Our advanced anti-caching measures ensure you get real, accurate measurements of your actual internet performance, not cached or optimized data.
Our Anti-Cache Techniques:
Random Data Generation
Every test chunk contains unique, cryptographically random data that cannot be cached or predicted by ISPs. Each byte is generated using secure random algorithms.
Unique Request IDs
Each request includes multiple unique identifiers (timestamp, nonce, UUID) preventing any form of response caching. No two requests are ever identical.
Cache-Busting Headers
Multiple HTTP headers ensure no intermediate proxy or CDN can cache the test data. Includes Cache-Control, Pragma, and Expires directives.
Multi-Threaded Testing
Parallel connections from different threads make it impossible to serve cached results consistently. Tests real-world concurrent usage patterns.
How The Test Works
4-phase comprehensive testing process
Latency & Jitter Test (10 pings)
Measures round-trip time and connection stability using multiple unique requests with varying cache-busting methods.
Download Speed Test (Multi-threaded)
Uses 4 parallel connections downloading unique random data chunks. Each chunk is guaranteed to be unique and non-compressible.
Upload Speed Test (Multi-threaded)
Uses 2 parallel connections uploading cryptographically random data that changes with each chunk, preventing any form of optimization or caching.
Results Analysis & Quality Assessment
Calculates final speeds, connection stability, and quality metrics. Detects inconsistencies that might indicate manipulation.
Comprehensive Metrics
Download Speed
Maximum data transfer rate from server to your device, measured in Megabits per second (Mbps).
Upload Speed
Maximum data transfer rate from your device to server, measured in Megabits per second (Mbps).
Ping (Latency)
Time for data to travel to server and back, measured in milliseconds (ms). Lower is better.
Jitter
Variation in ping times, indicating connection stability. Lower jitter means more stable connection.
Packet Loss
Percentage of data packets lost during transmission. Should be close to 0% for good connection.
Connection Stability
Consistency of speed across all test threads. Higher percentage indicates more reliable connection.
Quality Assessment
| Quality Level | Jitter | Packet Loss | Stability | Suitable For |
|---|---|---|---|---|
| Excellent | < 15ms | < 0.5% | > 90% | Gaming, Video Calls, 4K Streaming |
| Fair | 15-30ms | 0.5-2% | 80-90% | HD Streaming, Video Calls, Browsing |
| Poor | > 30ms | > 2% | < 80% | Basic Browsing Only |
