title: Chrome's HTML5 Web Database is very slow on some Windows configurations
body: <p>I am developing a Chrome app. I've noted that the app is about 1000 times slower when runing on Chrome for Windows XP. I have tested it on Chrome for Windows7, Ubuntu and Mac Os, it runs as expected there.</p>
  
  <p>Is there any known issue with Chrome's web database on XP?</p>
  
  <p>My app has only one table with about 500 rows and the query is very simple:
  SELECT * FROM users WHERE userid = ?
  userid is an index.</p>
  
  <p>UPDATE:
  Other important thing is that I run the same query about 1000 times, so must of them get delayed. I have reproduced the behaviour on Windows 7 too, so I'am not sure which configuration makes this to go so slow.</p>
