You can get some info from /etc/crontab

 # run-parts
 01 * * * * root run-parts /etc/cron.hourly
 02 4 * * * root run-parts /etc/cron.daily
 22 4 * * 0 root run-parts /etc/cron.weekly
 42 4 1 * * root run-parts /etc/cron.monthly

Note what is run at 4:02am /etc/cron.daily
weekly and monthy all ran around 4:+am
Now look inside /etc/cron.daily/ at the programs in there.

slocate and makewhatis are both heavy hitters in terms of cpu usage
and probably prime candates.  They update a rather hefty data base I think
One of them is the data based used for the `locate' command.  It keeps
daily track of where files are.

Not sure what `prelink' is.... mentioned in your post.
