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

[dependencies]
benchy = "0.1.0"

example

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

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

let mut bench = Benchy.new_duration(Duration::from_secs(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);
