Run each command under /usr/bin/time:

/usr/bin/time ls -l /usr/bin | awk '/^-.....[s]/ { print $3, $9 }'

/usr/bin/time find /usr/bin -perm +6000

My bets are on the find command - the ls command relies on a pipe to a 
completely different command, which is going to slow the whole process down 
a bunch.
