Hi

I am making a project wher I would like to measure the time of displaying big amount of data from DB in dataTable.

Could You give me the information:

1. how I can do it using JSF?

2. If there is something like "clock component" in JSF

3. where I can find it?

4. mayby somebody has the example of such a code ?

Thanx
