Interpreting a commandline speeds up if you use a constant found in  
the dictionary, as 1 or 2 or other constants you create. INTERPRET  
tries to FIND a WORD first, if that fails, tries to convert it as a  
NUMBER, and if that fails too you get an errormessage.

Try:
: example1  1 1 + . ;
: example2  1000 1000 + . ;
What runtimes did you find now?
