A benchmark utility for end points. Written in rust... rust + bench = rench
Installation requires either git or cargo.
Clone or fork the repo and run the following:
cargo install -f
cargo install -f rench
This should install and download from the latest release version.
The gist of a http benchmarker is to run a series of queries against an endpoint and collect the facts from it. These facts then are summarized for the user to examine. To really maximize an end point, we use a simple threading model to make many requests at the same time. This allows us to generate a large number of requests and try to fully saturate the http end point.
You can change the number of threads and the number of requests to suit your needs. You can even specify multiple URLs and it will round-robin the requests between them.
