VS 2010 - Add Controls/components (such As Performance Counters, Timers, Etc.)?

Which is less resource-intensive (per se):

> Add controls/components (such as Performance Counters, Timers, etc.) to a project by dragging them onto the form and using them by setting the properties and using code to program what they do.

> Add controls/components (such as Performance Counters, Timers, etc.) to a project by using Dim x As New Performance Counter or Dim y As New Timer in code without actually dragging them from the Toolbox onto the bar at the bottom (under the Form Design).Or is there another way to do this that uses less CPU/RAM/Resources/etc.?
