How to improve my "View Source" ??

A browser doesn't care what the (visual) formatting is, so that's a waist of time.
From a performance point of view it's even better to strip all formatting, so you have to send less bytes to the client.

Having said that, you could use the PHP Tidy module, or the mod_tiny apache module. You might be able to utilise a PHP beautifier like this one.

But this means processsing, which brings me back to my initial point...
