Here are some timings of random functions going in another direction.
Results for an old mac mini:
Works better on OS X.
Time for a 1000 X loop divided by 1000.
<nothing>134 ns
get empty 227 ns
get alphabet 288 ns
get random(9999999) 327 ns
get md5Digest(alphabet) 890 ns
get md5Digest(startLongSeconds & alphabet) 1837 ns
get md5Random() 2134 ns
on mouseUp
