Electron里面使用Socket为什么会阻塞？

在electron官方的脚手架使用了一个socket库，但是发现响应速度很奇怪，必须手动调用一个http跟另一个udp库接口刷新表格才会收到数据，感觉数据一直是阻塞状态，然后换回了net的Socket demo，同样是这个情况electron的依赖:

    "electron": "^2.0.4",
    "electron-builder": "^20.19.2",
    "electron-debug": "^1.5.0",
    "electron-devtools-installer": "^2.2.4",

下面是socket demo

var net = require('net')
        const ctime = new Date().getTime()
        console.log(ctime)
        this.client = new net.Socket()
        this.client = net.connect({ port: 29999, host: '127.0.0.1' }, function() {
          console.log('Connected:')
          console.log(' local= %s:%s', this.localAddress, this.localPort)
          console.log(' remote= %s:%s', this._remoteAddress, this._remoteAddress)
          this.setTimeout(500)
          this.setEncoding('utf8')
          this.on('data', function(data) {
            console.log(' From Server:' + data.toString())
            this.end()
          })
          this.on('end', function() {
            console.log('Client disconnection')
          })
          this.on('error', function(err) {
            console.log('Socket Error:' + JSON.stringify(err))
          })
          this.on('timeout', function() {
            console.log('Socket Timed Out')
          })
          this.on('close', function() {
            console.log('Socket Closed')
          })
        })
        console.log('连接成功')
        this.client.write('aaa')

当不调用http接口的时候：日志输出的是这时会一直阻塞，而且没有连接成功的输出，当调用一下udp库后就会连接成功同时清空页面用这个代码也是一样阻塞

<template>
  <div>
    <el-button type="success" round @click="test">测试</el-button>
  </div>
</template>

<script>

var net = require('net')

export default {
  methods: {
    test() {

      const ctime = new Date().getTime()
      console.log(ctime)
      this.client = new net.Socket()
      this.client = net.connect({ port: 29999, host: '127.0.0.1' }, function() {
        console.log('Connected:')
        console.log(' local= %s:%s', this.localAddress, this.localPort)
        this.setTimeout(500)
        this.setEncoding('utf8')
        this.on('data', function(data) {
          console.log(' From Server:' + data.toString())
          this.end()
        })
        this.on('end', function() {
          console.log('Client disconnection')
        })
        this.on('error', function(err) {
          console.log('Socket Error:' + JSON.stringify(err))
        })
        this.on('timeout', function() {
          console.log('Socket Timed Out')
        })
        this.on('close', function() {
          console.log('Socket Closed')
        })
      })
      console.log('连接成功')
      this.client.write('aaa')
    }
  }
}
</script>

但是用最原始的单元测试就一点问题没有，而且响应很快，能有人指导下吗？难道是因为electron渲染进程的问题？
