sandshark

  • zero dependencies!
  • aiming for 100% test coverage, currently @ ~70%
  • express.js syntax like with raw http performance
  • setup & middlewares should work right out of the box with your expressjs project
  • this is still "work in progress"!

currently in TODO

  • improving performance for inc. connections (not better than expressjs on benchmark results with keep-alive missing)
  • implement more express apis, a lot of stuff is still missing e.g. res.type(), app.disable()
  • implement custom cookie, query & body parser that can be toggled via config
  • microbench to reach 99,5% performance of raw http module
  • improve test coverage to 100%

run example

  • via npm start

run tests

  • via npm test

run benchmarks

npm run benchmark sandshark
npm run benchmark express
npm run benchmark raw
npm run benchmark restify
npm run benchmark hapi

  • or run all benchmarks in comparison via npm run benchmarks or npm run benchmark all

  • to compare expressjs and sandshark run npm run compare

  • each benchmark will spawn a server and worker making requests in their own child processes

  • the loadtest worker is limited to a single thread and makes at least 2500 requests

  • the benchmarks currently lack additional features such as body parsing, query params, path variables and cookies

  • there is a good chance to have far more place for optimizations

  • since hapi feels rather slow, feel free to send a pull requests if you think that I got something wrong

benchmark results

  • on a MacBook Air 11' 2014 Intel i5 quad @ 1.4 GHz
  • node version 6.5.0 & server modules are present in package.json devDependencies
[
  { raw: 1725 },
  { sandshark: 1692 },
  { express: 1223 },
  { restify: 1084 },
  { hapi: 687 }
]
  • with keep-alive turned off
[
  { express: 488 },
  { raw: 426 },
  { sandshark: 373 },
  { restify: 318 },
  { hapi: 314 }
]

disclaimer

  • i started this project after reading Node Performance hapi vs express vs restify
  • since their benchmarks are from March 2015, i guess they are outdated ;)
  • in their benchmarks raw http performance hits 8500 req/s and express only 3000 req/s
  • my benchmarks actually show expressjs way closer to raw http performance so another guess is that their benchmarks contain possible errors, sadly they have not posted them online

furthermore

  • i would love to have further discussions on this, so please feel free to open issues or hit me up on twitter @silentleave or my website
