comfy-bench v0.0.0

comfy-bench

Easy benchmarking

Features:

• Very easy to use
• Gives pretty accurate numbers
• Hit ctl-c to interrupt and get quick results
• Works with very fast and very slow operations
• Works with sync and async operations

Example: readfile.js

import * as bench from 'comfy-bench'
import fsprom from 'fs/promises'

bench.add('read /etc/hostname', () => {
  return fsprom.readFile('/etc/hostname')
})

bench.run()

output:

╔════════════════════╤═════════╤═══════╤═════════╗
║ Operation          │ ops/sec │ Range │ usec/op ║
╟────────────────────┼─────────┼───────┼─────────╢
║ read /etc/hostname │  17,506 │   ±2% │ 57      ║
╚════════════════════╧═════════╧═══════╧═════════╝

Example: system.js

import * as bench from 'comfy-bench'

bench.addSystemBenchmarks()

bench.run()

output:

Discarding best and worst samples, since we have 5 or more
