Hello,

25% speedup is in processing large arrays with lots of floating point 
calculations. It also depends on CPU used. On some CPUs 64-bit version
may use SSE/SSE2/SSE3 extensions giving better results. There are way too many 
combinations of CPUs/formulas that you use/amount of data/etc
to get a single "speedup" number. Therefore I use "a bit faster" because it is 
always true.

CMAE is included in 64-bit version.

Best regards,
