plow
Plow is an HTTP(S) benchmarking tool, written in Golang. It uses excellent fasthttp instead of Go's default net/http due to its lightning fast performance.
Plow runs at a specified connections(option -c) concurrently and real-time records a summary statistics, histogram
of execution time and calculates percentiles to display on Web UI and terminal. It can run for a set duration(
option -d), for a fixed number of requests(option -n), or until Ctrl-C interrupted.
The implementation of real-time computing Histograms and Quantiles using stream-based algorithms inspired by prometheus with low memory and CPU bounds. so it's almost no additional performance overhead for benchmarking.
