Speed question? xml vs. python

I have an addon that runs a timing sensitive routine. I have 2 screens coded in xml. These screens share several common features such as progress bars.

Right now I have about 30 text fields that I reconfigure when switching from one screen configuration to the other. I do this with 30 lines of xbmcgui.window(10000).setProperty(‘field’,’value’) statements in my Python code.

My question is would my code execute faster if I hard coded the different text fields in my xml code and simply toggled the visibility field of each set from my python code? Then I’d only need one or 2 lines of Python code to select between the 2 screen configurations but my xml code would be 2 x longer.

Please let me know if you think this would be better posted in the skinning section (I’m a newbee).
