level-benchmarks

Run benchmarks against levelup-compatible engines

Kudos

This is based upon the tests in levelup, but extended with more tests.

Installation

npm install level-benchmarks

Example

Input

var engines = [
        {
            name: 'levelup (leveldown)'
          , factory: require('level')
        }
      , {
            name: 'levelup (memdown)'
          , factory: require('level-mem')
        }
    ]
  , lengths = [ 10 ]
  , benchmarks = require('./benchmarks')

benchmarks(engines, lengths, { maxTime: 1 }, function (err, result) {
  console.log(benchmarks.format(result))
})

Output

levelup (leveldown) put(int, string) x 10 x 604 ops/sec ±2.63% (18 runs sampled)
