GB，千兆字节的缩写，是数字数据的计量单位。1 GB 等于大约十亿字节。它通常用于描述文件的大小、存储设备的容量或通过网络传输的数据量。在代理网络中，GB 通常用于跟踪数据使用量或带宽限制。

用例
Measuring Bandwidth Consumption
Proxy providers track how many gigabytes of data you send and receive. Monitoring this helps users predict costs, optimize performance, and prevent early bandwidth depletion.
Estimating Data Requirements for Web Scraping
When planning a scraping project, teams estimate how many gigabytes are needed to complete the job. A lightweight API crawl might consume a few GB, while e-commerce or travel data extraction could require hundreds.
Managing Multi-Account or Automated Activity
Automation tools that manage social, retail, or ad accounts use proxies to route traffic. Gigabyte usage indicates how efficiently requests are being handled across multiple sessions or devices.
最佳实践
Monitor Bandwidth in Real Time
Use your proxy dashboard or API to keep track of consumed gigabytes. This helps avoid throttling or plan suspension due to unexpected overuse.
Optimize Request Efficiency
Compress responses, limit unnecessary headers, and cache frequent requests when possible. These small improvements can save dozens of gigabytes over time.
Choose the Right Proxy Type
If your project moves large volumes of data (e.g., product images, logs, or analytics exports), opt for datacenter or ISP proxies with higher bandwidth limits. For smaller, location-sensitive tasks, residential proxies with moderate GB caps are often more cost-efficient.
结论
A gigabyte measures how much data flows through your proxy connection—essentially, the total “weight” of your requests and responses. Understanding and optimizing your gigabyte usage helps control costs, maintain speed, and ensure your scraping or automation runs smoothly.

经常问的问题
Why do proxy plans include a GB limit?
+
Because every request routed through a proxy server consumes bandwidth. Providers cap gigabytes to manage load, prevent abuse, and align pricing with data transfer costs.
How can I reduce gigabyte usage?
+
Use caching, filter unnecessary endpoints, and optimize your scraper to avoid downloading heavy assets like images or scripts when you only need HTML or JSON data.
Why does my proxy dashboard show slightly different GB usage than my script logs?
+
Different systems calculate a gigabyte using either 1,000 MB or 1,024 MB, and some may round up response sizes or count TCP overhead — causing minor discrepancies.
How many requests fit into one gigabyte?
+
It varies. A single HTML page might be 100–300 KB, while a full product page with images can exceed 2 MB. Roughly speaking, 1 GB could handle anywhere from 500 to 10,000 requests depending on the page weight.
