OK - I surrender.

I did my own little test of 5.11 floats vs. 5.11 doubles with Xanadu 
(regular version). On my Windows XP desktop, the doubles version is indeed 
ever-so-slightly *faster*.

Results:
5.11 floats (commandline): real 25.924  CPU: 25.922
5.11 doubles (commandline): real 25.565  CPU: 25.563

My desktop is probably average for today's technology: Athlon 64 x2 Dual 
Core Processor 5200+ 2.71GHz, with 2GB RAM.

So my vote is for doubles as well.

Can I still assume, however, that for 5.11 and *"older"* technology, such as 
the XO's and netbooks, that floats maintain their speed advantage?  (This is 
what my previous tests showed, though with earlier versions of Csound5.)
