Node.js Server Cluster test Benchmark using AB(Apache Banchmark)

server code(no cluster)
var http = require("http");

http.createServer(function(request, response) {
    var s = 64*1024;
  var buf = new Buffer(s);
  for(var i=0;i<buf.length;i++){
    buf[i]=100;
  }
    //console.log("Request for:  " + request.url);
    response.writeHead(200);
    response.end(buf);
  }).listen(3000);
