I. Introduction to Throughput in Technical Context The term "throughput" in English technical discourse refers to the volume of data processed by a system within a specific time frame, typically measured in bits per second (bps) or bytes per second (B/s). This critical performance metric is fundamental to evaluating the efficiency of network infrastructure, computational systems, manufacturing processes, and transportation networks. In English-speaking engineering communities, throughput is often abbreviated as Thp (throughput) and contrasted with latency (time delay) and bandwidth (maximum data transfer capacity). For instance, a 1 Gbps Ethernet port theoretically offers a maximum throughput of 125 MB/s ( megabytes per second) when transferring uncompressed data, though real-world performance may be lower due to protocol overhead and network congestion.
II. Quantitative Measurement Framework
-
Basic Calculation Formula Throughput (Th) = Total Data Transferred (D) / Time Interval (T) When measuring network throughput, engineers often use the following改良型公式: Effective Throughput = (Received Data - Protocol Overhead) / (Transmission Time + Latency)

Standard Testing Protocols In English technical documentation, two primary methodologies are recommended:
- Iperf Test: A command-line tool simulating continuous data streams to measure maximum sustainable throughput
- JMeter Scripts: For application-level load testing with customizable transaction rates Notably, the Tolly Group's certification standards require at least 30-minute sustained testing periods to account for thermal throttling in modern processors.
Unit Conversions Commonly used units include:
- 1 Mbps = 1,048,576 bits/second (binary)
- 1 MB/s = 1,048,576 bytes/second (binary)
- 1 Gbps = 1,000,000,000 bits/second (decimal) The discrepancy between binary and decimal measurements (e.g., 1 GiB vs 1 GB) creates frequent confusion in English technical discussions.
III. Multi-Dimensional Influencing Factors
Network Architecture Components
- Router/NIC Bottlenecks: A 10Gbps NIC with TCP/IP overhead might achieve only 8.5Gbps effective throughput
- Switch Queue Depth: 64-entry queues in enterprise switches can cause 15-20% throughput reduction during packet collisions
- CDN Caching Efficiency: Google's BBR (Bandwidth-Based Round Trip Time) algorithm improves throughput by 18-25% in mobile networks
Data Protocol Characteristics
- TCP Versus UDP: TCP's 20-30 byte header adds significant overhead (15-20% for small packets)
- HTTP/2 Multiplexing: Reduces latency by 40% but increases throughput by only 5-8% through parallel streams
- MQTT协议: Used in IoT devices, its 3-byte header results in 75% higher throughput compared to HTTP
Environmental Variables
- Thermal throttling: Intel Core i9 processors maintain 90% throughput at 65°C but drop to 60% at 85°C
- Power Supply Constraints: A 500W server PSU cannot sustain 40Gbps throughput for more than 15 minutes
- Physical Distance: 10G Ethernet over OM4 fiber degrades to 6.25Gbps at 550 meters
