Document Classes ⇒ Too many subsections in beamer and Warsaw theme

[turbomac]

Hello Everyone:


I want to make a presentation using beamer and Warsaw theme. The thing is I have lots of subsections, so the space for the contents of the presentation is very reduced because the subsection ribbon uses a big space. The same thing would occur if I had a lot of sections.

Is there any way to reduce this ribbon? I attach a minimal example code.

Cheers!
