Boom is a tiny program that sends some load to a web application. It's similar to Apache Bench (ab), but with better availability across different platforms and a less troubling installation experience.
Boom is originally written by Tarek Ziade in Python and is available on tarekziade/boom. But, due to its dependency requirements and my personal annoyance of maintaining concurrent programs in Python, I decided to rewrite it in Go.
Simple as it takes to type the following command:
go get github.com/rakyll/boom
Boom supports custom headers, request body and basic authentication. It runs provided number of requests in the provided concurrency level, and prints stats.
Usage: boom [options...] <url> Options: -n Number of requests to run. -c Number of requests to run concurrently. Total number of requests cannot be smaller than the concurency level. -q Rate limit, in seconds (QPS). -o Output type. If none provided, a summary is printed. "csv" is the only supported alternative. Dumps the response metrics in comma-seperated values format. -m HTTP method, one of GET, POST, PUT, DELETE, HEAD, OPTIONS. -h Custom HTTP headers, name1:value1;name2:value2. -t Timeout in ms. -A HTTP Accept header. -d HTTP request body. -T Content-type, defaults to "text/html". -a Basic authentication, username:password. -x HTTP Proxy address as host:port. -readall Consumes the entire request body. -allow-insecure Allow bad/expired TLS/SSL certificates. -disable-compression Disable compression. -disable-keepalive Disable keep-alive, prevents re-use of TCP connections between different HTTP requests. -cpus Number of used cpu cores. (default for current machine is 1 cores)
This is what happens when you run Boom:
