Does py2app improves speed?

[Ricardo Mansilla]

Hi everyone..
My question is exactly as in the subject of This Mail. 
I have made a Python  script which is to slow and i have heard (and common 
sense also suggest) that if you use some libraries to "frozen" the script the 
performance improves substantially. So I need to know; is This a myth or it is 
a fact?
Thanks in advance for your time.
