For some reason mlocate is taking a long time when I run the updatedb command. Have a look!

[root@beta:~] #time updatedb real 19m48.729s user 0m0.400s sys 0m2.728s

Does

# time /etc/cron.daily/mlocate.cron

take the same amount of time? It calls updatedb with a list of file systems to be skipped.

When updatedb is running, get the PID of the process, and try to follow the files the process has opened by:

# ls -l /proc/PID/fd

Do this now and then when updatedb runs this might give you an idea where in the file system it spends most of the time.
