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)
levelup (memdown) put(int, string) x 10 x 660 ops/sec ±1.33% (22 runs sampled)
levelup (leveldown) get(int):string x 10 x 589 ops/sec ±1.51% (18 runs sampled)
levelup (memdown) get(int):string x 10 x 667 ops/sec ±2.39% (16 runs sampled)
levelup (leveldown) batch(int, string) x 10 x 652 ops/sec ±3.77% (13 runs sampled)
levelup (memdown) batch(int, string) x 10 x 681 ops/sec ±4.48% (16 runs sampled)
levelup (leveldown) readStream x 10 x 564 ops/sec ±2.16% (19 runs sampled)
levelup (memdown) readStream x 10 x 610 ops/sec ±1.81% (20 runs sampled)
