async_benchmark

async_benchmark is a Dart package for running and analyzing benchmarks with support for isolated environments and performance tracking.

Usage

import 'dart:math';

import 'package:async_benchmark/async_benchmark.dart';

void main() async {
  final profile =
  BenchmarkProfile('custom', warmup: 10, interactions: 100, rounds: 3);

  await BenchmarkPrime(seed: 12345).run(profile: profile, verbose: true);
}

class BenchmarkPrime extends Benchmark<int, Prime> {
  final int? seed;

  BenchmarkPrime({this.seed}) : super('PrimeCounter(seed: ${seed ?? '*'})');

  @override
  BenchmarkSetupResult<int, Prime> setup() {
    var prime = Prime();

    var rand = Random(seed);
    var limit = rand.nextInt(999999);

    return (setup: limit, service: prime);
  }

  @override
  void job(int setup, Prime? service) {
    var prime = service ?? Prime();
    prime.countPrimes(setup);
  }
}

class Prime {
  int countPrimes(int limit) {
    var count = 0;
    for (var n = 2; n <= limit; ++n) {
      if (isPrime(n)) {
        ++count;
      }
    }
    return count;
  }

  bool isPrime(int n) {
    if (n <= 1) return false;
    if (n == 2) return true;

    if (n % 2 == 0) return false;

    var sqr = sqrt(n);

    for (var b = 3; b <= sqr; b += 2) {
      if (n % b == 0) return false;
    }

    return true;
  }

  @override
  String toString() => 'Prime{}';
}
