Multiple or one Dialog objects

Perhaps a stupid question, but bear with me please:
Let´s say I have 20 links on a webpage that needs to trigger a Dialog,
with different options and content. Is it quicker, JavaScript
performance-wise in different browser, to make one object, close it,
adjust the settings with setters and open it again, or initiate a new
object with the correct settings and destroy it each time?
