hi,
I've got a DB driven web application which currently has approx 298 inserts
per day and 540 edits/deletes.
This figure will change daily and currently i have a cron job set up to
vacuum the database every hour during 'work time':
0 7-19/1,23 * * * /usr/local/pgsql/bin/vacuumdb -z -d edb
30 7-19/4,23 * * * /backup/dumpit
I've also started reading Bruce's book (and what a fine book it is ... :-)
and noticed that he suggests vacuuming once a day when the db is quiet.
Would this be sufficient ? The database drives a web based
calendar/appointment booking/reporting system i've written in php and is
used extensively by 3 departments and has approx 200 people log in each day.
Needless to say speed it paramount but I've got a sneaky feeling I might be
vacuuming too often ....
Many thanks for you help,
Steve
