Keep in mind, though, that turning on tracing has its own impact
(negative) on performance. So if all you care about is a general delta
between the two techniques, you may be able to get a rough idea from
looking at the trace log. But it won't give you an accurate picture of
how the pages actually perform.

For a more accurate picture, it would be better to build one page for
each technique, then hit those pages with a load testing tool such as
the Web Application Stress Tool (http://webtool.rte.microsoft.com/).
This will allow you to test both the overall performance of the two
techniques, as well as to see whether either or both perform well or
poorly under load.

What's the performace difference between

Using Repeater and binding the data reader to it

Vs

Using Label server control and build the html using

Label.Text+=3D"<html>" + datareader["field"];

Thanx
