Go is fast

Speed is one of the primary objectives of the Go programming language. Many benchmarks put the speed of Go on par with that of C++, Java, and Rust, and miles ahead of languages such as Python and Ruby. Benchmark tests should always be considered with a bit of skepticism, but Go consistently stands out as a language with extremely high-performance numbers. This speed is typically coupled with a low resource footprint, as the runtime is very lightweight and does not use much RAM. One of the hidden benefits of this is being able to run Go programs on smaller machines, or to run multiple instances on the same machine, without significant overhead. This reduces the cost of operating a web scraper at larger scales.

This speed is inherently important in building web scrapers, and becomes more noticeable at larger scales. Take, for example, a web scraper that requires two minutes to scrape a page; you could theoretically process 720 pages in a day. If you were able to reduce that time to one minute per page, you would double the amount of pages per day to 1,440! Better yet, this would be done at the same cost. The speed and efficiency of Go allow you to do more with less.
