node.js - nodejs前端频繁post 导致很卡的问题

Question

前端js，post过去，频繁的点击，就很卡。
这是nodejs的代码：

    var express = require('express');
    var bodyParser = require("body-parser");
    var app = express();

    app.use(express.static('app'));
    app.use(bodyParser.urlencoded({ extended: false }));

    var server = app.listen(config.socket_port, function () {

      var host = server.address().address
      var port = server.address().port

      console.log("应用实例，访问地址为 http://%s:%s", host, port)

    })

    var post_callback = function (post_res, err, res){
        return post_res.end(JSON.stringify({err:err, res:res}));
    }

    app.post('/post', function(req, post_res) {

        let data = req.body;
        let filter = JSON.parse(data.filter);

        return post_callback(post_res, null, []);
    });

这是前端的代码，jquery

$.post(configObj.socket_url+'post', {dbname: _this.dbname, action:_this.dbname+'__get', filter:JSON.stringify(filter)},function(res){
            let jsonObj = JSON.parse(res);
            console.log(jsonObj);
            callBack(jsonObj.err, jsonObj.res);
        });

仔细分析，我没发现哪里出现性能问题。我只是用鼠标快速的点几十下而已。页面就卡了。电脑都非常的卡。

The page lag has nothing to do with the server. In addition, similar application scenarios in actual applications will limit requests to avoid continuous invalid clicks
