You can use firebug which will give you the exact time, from the users' perspective.

If you want the server-side generation times, you can use a Filter. In its doFilter(..) method have something like:

long start = System.nanoTime();
chain.doFilter(request, responsE);
long time = System.nanoTime() - start;
