You might want to compare the wall-clock times, because that is what 
the user experiences. User and system times are completely unimportant 
from the user's POV (though they're interesting for the admin of a 
multiuser system)

Suddenly the difference is ca. 0.4 seconds. Granted, this isn't much 
either, but the full second on the first measurement would be quite 
worth it, no?

... or 0.207 (wall clock) seconds or 10% speedup.
