![]() ![]() You won't have quite as much control as you will with a fully customized client but it's worth having in your toolbox. This can be helpful if you are instrumenting code that uses http.Client or if you need to support proxies, TLS, keep-alive or other HTTP capabilities but don't want/need to re-implement them all. I will, however, state that Go 1.1 continues to outpace Node.js, and even the HTTP layer seems to have been 1-upped now. GitHub - nDmitry/web-benchmarks: A set of HTTP server benchmarks for Golang, node.js and Python with proper CPU utilization and database connection pooling. For now, I just want to start some goroutines in this order: Main: start a benchmark (goroutine) for each web site pages, get the average execution time and print it. Using Lighthouse, GTmetrix generates scores for your pages and offers actionable. ![]() The chart below compares the first-paint times. GTmetrix is a free tool to test and monitor your pages performance. Not to take anything away from the perfectly valid accepted answer, one alternative to be aware of is to implement a custom RoundTripper that wraps the default http.Transport and net.Dialer. Basically, Im making HTTP requests (GET method) to multiple URLs on multiple web sites. HTTP client comparison with net/http In short, fasthttp client is up to 10 times faster than net/http. According to a research conducted by Microsoft, 500msec slowdown in Bing causes their revenue go down by 1.2.
