# RAB - Rust Apache Bench
The goal of this program is to become a drop-in replacement for [apache bench (ab)](https://en.wikipedia.org/wiki/ApacheBench).
## Background
This program is based on [mio](https://docs.rs/mio), which is a library for non-blocking IO.
On linux, that would be [epoll](https://man7.org/linux/man-pages/man7/epoll.7.html).
A notable difference with `ab`, and the reason I wrote this in the first place, is that `ab` does not start shooting at full throttle right away.
Instead, it first "tests" the connection by awaiting the first request. Only once that succeeds, the remaining connections are started ([read more](https://mail-archives.apache.org/mod_mbox/httpd-users/202103.mbox/browser)).
## Usage
Fire 10 requests over two connections:
```bash
cargo run -- -c 2 -n 10 "google.com"
```
Show Options:
```bash
cargo run -- --help
```
## Sample Output
```bash
> cargo run --quiet -- -c 100 -n 10000 "localhost:8080"
