Measuring outside mzscheme, using the Unix 'time' command, with 
something as simple as

time mzscheme -e '(display "text\n")'

shows the difference in the "user" time reported. (It is about 1 second 
for the locally-built version and close to 2 seconds for the installed 
version -- those seem excessive compared to 0.3 seconds on my laptop, 
but there the JIT can do its magic...).

I'll try the expression quoted above. --PR
