Ahh.. Debian. Good man. :)
I suspect that it's the updatedb utility. Every day, though it
should be, I thought, about 6:30am, updatedb will launch (check
your /etc/cron.tab and/or /etc/cron.daily/ directory), and go
through your entire set of file systemS (!), and collate a nice
little flat database of your filenames. It stores this in (from
memory) /var/lib/updatedb (or thereabouts). When you use the
'locate <filename>' utility, all that does is searches through
said database (so it's up to 24 hours out of date).
My gut feel is your clock is wrong and/or you are using your
computer at silly times of the day (read 7am) and/or you haven't
told updatedb.conf (in /etc) to not search ncpfs, nfs, iso9660,
etc, file systems. That can slow you down a smidge... (speaking
from experience - since updatedb.conf lists exclusions, rather than
inclusions, I didn't notice immediately that my little P75 at work
was trying to examine about a dozen 4gig Netware3 boxes, all at
the ends of 64k links in different countries - trez embarrassing. :)
