nodejs http2下载慢

Question

使用curl非常快
curl --http2 -O "https://t1.daumcdn.net/potplayer/PotPlayer/Version/Latest/PotPlayerSetup64.exe"

nodejs

const fs = require('fs')
const http2 = require('http2')

function error({ message }) {
  console.log(message)
}

const url = new URL('https://t1.daumcdn.net/potplayer/PotPlayer/Version/Latest/PotPlayerSetup64.exe')
const {
  HTTP2_HEADER_STATUS,
  HTTP2_HEADER_AUTHORITY,
  HTTP2_HEADER_SCHEME,
  HTTP2_HEADER_PATH
} = http2.constants

const h2 = http2.connect(url)

h2.on('error', error)

const req = h2.request({
  [HTTP2_HEADER_AUTHORITY]: url.host,
  [HTTP2_HEADER_PATH]: url.pathname,
  [HTTP2_HEADER_SCHEME]: 'https',
})

req.on('response', (headers) => {
  console.log(headers[HTTP2_HEADER_STATUS])

  const file = fs.createWriteStream('file')

  req.pipe(file)

  req.on('end', () => {
    h2.close()
  })
})

req.on('error', error)

req.end()

使用https模块会快一点 但是没有curl快
什么原因呢
