Just a little benchmark... but its not working

test_bench.js

var http = require('http'),
CONFIG = require('./config'),
Client = require('mysql').Client,
fs = require('fs'),
client = new Client(CONFIG),
TEST_DB = 'node_test',
TEST_TABLE = 'test',
count = 0;

client.connect();

client.query('CREATE DATABASE ' + TEST_DB, function(err) {
  if (err && err.number !== Client.ERROR_DB_CREATE_EXISTS) {
    throw err;
  }
});

client.query('USE ' + TEST_DB);

client.query(
  'CREATE TABLE '+  TEST_TABLE+
  '(id INT(11) AUTO_INCREMENT, '+
  'title VARCHAR(255), '+
  'text TEXT, '+
  'created DATETIME, '+
  'PRIMARY KEY (id))'
);

http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  client.query(
  'INSERT INTO ' + TEST_TABLE + ' ' +
  'SET title = ?, text = ?, created = ?',
  ['TEST' + count++, Math.random(), new Date().toUTCString()]);
  fs.readFile('./data', function(err, data) {
    if (err) throw err;
    res.end(data);
  }); 
}).listen(3000);
console.log('Server running on port 3000');

/* running 'ab -r -n 100000 -c 1000 http://127.0.0.1:3000/' results in
