AutoCannon

An HTTP/1.1 benchmarking tool written in node, greatly inspired by wrk and wrk2, with support for HTTP pipelining and HTTPS. If the PORT environment variable is set, the URL can be a path. Use a warm up interval before starting sampling. This enables startup processes to finish and traffic to normalize before sampling begins. There are two tables, one for the request latency, and one for the request volume. The latency table lists the request times at the 2.5% percentile, the fast outliers; at 50%, the median; at 97.5%, the slow outliers; at 99%, the very slowest outliers. Here, lower means faster. When in workers mode, you need to pass in an absolute file path to all the options that accept a function. This is because a function passed into the main process can not be cloned and passed to the worker. So instead, it needs a file that it can require. When combining a fixed amount of requests with concurrent connections and an overallRate limit, autocannon will distribute the requests.
