I don't find this neither surprising nor silly.  When you use a float 
format, `fprintf' has a lot of FP computations to do, and they all are 
emulated when you don't have a co-processor.  The usual ratio of run 
times between a machine with FPU and one without it, when they run an FP 
program, is about 20-30.  You see 6min / 10sec = 36, which is only 
slightly higher (probably, due to the fact that you eliminate the %f 
processing altogether rather than doing it with an FPU).

So I would say this is expected behavior.
