Benchmark support library for Rust

Features

• iterator style
• result analysis
  • count, mean, mode
  • median, N-percentile (error 1-2%)
• getrusage
  • CPU time (usr/sys)
  • Memory (RSS usage, min/maj fault, swap)
  • I/O (block in/out, message send/recv)
  • Context switch (signals, voluntary/involuntary switches)

Usage

Cargo.toml

toml [dependencies] benchy = "0.1.0"

example

```rust use benchy::Benchy; use std::time::Duration;

for i in Benchy.newduration(Duration::fromsecs(5)) { // some works } // auto print result to stdout (5 secs after)

let mut bench = Benchy.newduration(Duration::fromsecs(5));

for i in bench { // some works } // show detailed result (5 secs after) println!("median(50-th percentile): {}", bench.median()); println!("90-th percentile: {}", bench.percentile(90.0)); println!("95-th percentile: {}", bench.percentile(95.0)); println!("99-th percentile: {}", bench.percentile(99.0));

// rusage difference (end - start) println!("rusage = {} {:?}", bench.usage, bench.usage); ```
