The 4.2 C compiler  on the 3B2 can optimize code for faster performance. 
The code generated in many cases is noticeably faster than 4.1 generated code.
Possibly 50% faster (NO PROMISES).

If your program spends a lot of time doing user calls (see "time" in man),
you may get improved performance by adding the co-processor.
