you can always use console.time('timerName') and console.timeEnd('timerName') to set a timer and find out elapsed time between two points of your javascript code, then compare the results:

console.time('BigArray');
var arr1 = [];
for(var i=0; i<200000; i++){
    arr1.push('test');
}
console.timeEnd('BigArray');


console.time('SeveralArrays');
for(var i=0; i<200000; i++){
    var arr2 = ['test'];
}
console.timeEnd('SeveralArrays');

the output will be something like:

BigArray: 123ms
SeveralArrays: 456ms

browser behavior is different from curl. browser will not render the page, until you call res.end(). so if you want to load a part of a web page after a delay, you need to load that second part separately via a websocket or an ajax request. I recommend using websocets. take a look at socket.io, it's a simple way of using websockets in node.js.

You should call push() inside your click() event to make it run on every click:

$(document).ready(function(){
    if(typeof arr == "undefined"){
        var arr = new Array();
    }

    $("#submit").click(function(){
       arr.push(2);
       console.log(arr);
    });
});
