If you are using getpwent the above will help you. However applications such as
cron use initgroups/getgrent to initialize your group entries. If you
have a large group file then you will see a fair amount of data 
transfer during the initgroups call. This is improved in 10.3 (thx for
the info Joe) but if you are running at 10.1 and 10.2 applications such
as cron will pull the entire groups file everytime they have an entry
to be executed.

regards.
