How We Measure True Multi-Stream Speed, Bufferbloat & Local Tower Congestion
Welcome to SoftSutra Speed Test (speed.softsutra.online), an open-telemetry network diagnostic platform engineered by SoftSutra under the leadership of founder Raman Sharma. Unlike basic browser timers that download a single static file and often report inaccurate numbers due to ISP caching or TCP slow-start bottlenecks, SoftSutra Speed Test implements an RFC-inspired multi-stream throughput engine paired with hyper-local Village and Ward-level Cell Tower aggregation.
1. Multi-Stream TCP Saturation & 85th Percentile Trimming
Modern 4G LTE Advanced, 5G NR, and high-capacity wireless links cannot be saturated by a single HTTP thread because of the Transmission Control Protocol (TCP) congestion window and slow-start algorithm. During the first 1,000 to 1,500 milliseconds of any data transfer, the network stack gradually probes link capacity. SoftSutra opens up to six concurrent parallel binary streams across edge nodes, samples instantaneous throughput every 150 milliseconds, discards the initial warm-up ramp, and computes the steady-state 85th percentile transfer rate. Furthermore, all upload payloads are generated in real time using cryptographically random byte arrays (crypto.getRandomValues) so intermediate carrier proxies and Gzip/Brotli middleboxes cannot compress the payload and fake higher speeds.
2. Unloaded Latency, Jitter & Loaded Bufferbloat Analysis
Raw bandwidth in Megabits per second (Mbps) only tells half the story. For real-time applications such as VoIP calls, live classes, stock trading, and competitive gaming, packet queuing delay-known as Bufferbloat-is the primary cause of lag. Our engine first measures Unloaded Ping and Jitter (the variance between consecutive round-trip times) when your connection is completely idle. Next, while the download and upload pipes are 100% saturated, our engine fires background edge probes to measure Loaded Latency. If your ping jumps from 25 ms to 400 ms during a download, your local cell tower sector or router suffers from severe bufferbloat.
3. Why Broadband Plans Are Excluded from Cell Tower Averages
A critical flaw in traditional crowd-sourced speed maps is mixing fixed-line Fiber-to-the-Home (FTTH) broadband connections with mobile cellular networks. A user on a 499 broadband plan receives a strictly throttled 30 Mbps speed, whereas a neighbor on a 999 plan receives 150 Mbps on the exact same optical line. Averaging those numbers measures consumer billing plans rather than network capability. Conversely, wireless 4G and 5G cell towers dynamically fluctuate based on RF signal-to-noise ratio (SINR), carrier aggregation bands, and evening peak-hour congestion. SoftSutra automatically distinguishes mobile cellular ASNs and radio interfaces from fixed broadband connections-ensuring our Village & Ward Tower Averages reflect genuine mobile tower performance.
4. Geohash-6 Cell Tower Sector Mapping & Open Data
When you grant GPS permission on SoftSutra Speed Test, your coordinates are converted in-browser into a 6-character Geohash sector (approximately 600 meters by 1.2 kilometers-matching the typical coverage footprint of a rural village or urban municipal ward cellular sector) alongside reverse-geocoded administrative boundaries. Only aggregated statistical counters and anonymized network logs are stored, empowering rural and urban citizens across India to verify which telecom operator delivers the fastest real-world speeds during morning, afternoon, evening peak, and late-night hours.
