anyone benchmark this?

so slow....

express-static qps = 6199.4
express qps = 7566
koa2-router-static qps = 2800.6
koa2-router qps = 7073.2
koa2-static qps = 2600.6
koa2 qps = 9603.6

const Koa = require('koa')
const serve = require('koa-static')

const app = new Koa()

// $ GET /package.json
app.use(serve('.'))

// response
app.use(ctx => {
  ctx.body = 'Hello Koa'
})

// app.listen(3000)
module.exports = app.callback()

const Koa = require('koa')
const router = require('koa-router')()
const serve = require('koa-static')

const app = new Koa()

// $ GET /package.json
app.use(serve('.'))

router.get('/', function (ctx, next) {
    ctx.body = 'Hello Koa'
})

app
  .use(router.routes())
  .use(router.allowedMethods())

// app.listen(3000)
module.exports = app.callback()

Slow? So your service does over 224,640,000 requests per day on a single node? With no CDN? :p

[狼叔]

@tj i mean koa is so fast, but when i mount static middleware, it's really slow 4x: 9600/2600. maybe we can optimization performance with koa-send & koa-static

[TJ Holowaychuk]

2600 rps isn't slow though, that's the 224M requests / day. Just my .02 but I think anyone with that kind of traffic would have a CDN going, or at least two nodes for redundancy, which would then support half a billion per day.

Also try the defer: true option so it does not sit in front of every request, that should reduce the latency there.

app.use(serve('.'))

IMO, this is a bad practice, as every request will hit koa-static and will be checked does request.url exists (a file or a directory).

var stats = yield fs.stat(path);

The better way used is combine with a router, eg:

router.get('/public/*', async function(ctx, next) {
ctx.url = path.basename(ctx.url)
await next()
}, staticServer(resolve('./public'), {gzip: true}))

yes, filtering your routes and using defer: true will help increase performance
