I dunno about the best or most efficient, but...

...I use a small script from the directory in question...

du -s * | sort -rn | head -40 > piggy.list

...most often just at the commandline, but for specific filesystems, 
like keeping track of mail folders, website dirs or logs, I use a 
script to mail me the output and add it to the cron table to run once 
a week (or whatever).

So, for example,

----------
#!/bin/sh
# mail list of 20 largest mailboxes

IFS='
'
PATH=/bin:/usr/bin:/usr/local/bin

host=`hostname`

cd /var/mail

du -s * | sort -rn | head -20 | Mail -s "$host: 20 biggest mailboxes" myself at mydomain.net

----------

...and have it run as a cron job.

0 3 * * 1 /local/sbin/maildu.sh

Hope that helps!
