HTTP Load Tester

• An HTTP Load Tester written in Go that supports concurrent requests, and outputs important metrics
• Check if your system handles concurrent load properly, or if your rate limiting works correctly

Usage

Options
  -n int
    	Total number of requests to make (default: 5)
  -c int
    	Number of concurrent requests (default: 1)
  -url string
    	Endpoint URL for load testing

Example

$ go build .
$ ./http-load-tester -n 1000 -c 100 -url=http://localhost:12345

Installation

$ git clone https://github.com/me-heer/http-load-tester.git
$ cd http-load-tester
$ go build .
$ ./http-load-tester -n 1000 -c 100 -url=http://localhost:12345

Sample HTTP Server

• If you need, sample_http_server/ has a test http server which you can use to observe the behavior of HTTP Load Tester.
• Start the sample HTTP Server by: go run sample_http_server/http_server.go

Notes

• There is no limit on the number of concurrent requests you can send. However, the number of parallel requests will mostly be determined by your system's CPU. Hence, -c flag can also be interpreted as "roughly parallel requests"
• Please be responsible while load testing websites and only send requests to servers that you own/have permission to do so. If you're curious about sending large amounts of requests, you can use sample_http_server/http_server.go.
