title: GWT Grid - how to measure rendering time on client
body: <p>we've got an application developed in java, with GWT providing the frontent. The application is used on a variety of hardware specifications, e.g. also on older machines. Of course users complain about performance.</p>
  
  <p>We'd like to collect profiling data from real-world users. So far we can measure the pure server-side duration (that's easy) and the duration of the network roundtrip (not so easy, but we managed that).</p>
  
  <p>The hardest part for us is measuring the time elapsed between "user clicking on search button" and "first xxx rows of grid have been displayed". </p>
  
  <p>Any idea?</p>
  
  <p>Thanks
