Re: Memory usage for Domino

Don't Add ALL the views. only the "default" view, for a mail file that is
$INBOX.

Users do NOT open all the views in a mail file at once, and rarely open
views other than $inbox and calendar.

Just track the size of $inbox.

Thank you Walter.

In my Admin (we're a daos shop) if I sort by "Logical Size" the largest
mail file is 6.2GB. It's physical size is only 42MB. The view indexes
of this database consume 5 MB of disk space, which is 0% of the entire
space used by this database.
The largest physical file is 624MB and it's logical size is 1.3GB. The
view indexes of this database consume 85 MB of disk space, which is 7% of
the entire space used by this database.
The median physical file is 51MB. The view indexes of this database
consume 13 MB of disk space, which is 4% of the entire space used by this
database.
The median logical size is 240MB. The view indexes of this database
consume 7 MB of disk space, which is 3% of the entire space used by this
database.
13MB x 2 x 400 users = 10.4GB?

We archive mail that is over 6 months old. We put no size or other type
restrictions. We've brought that up to management but their concern was
that a major customer might send us a drawing and we wouldn't want to
reject it (how big do we need to make the check for the disk drives?).

We have 453 mail files. It's 9am here. Which is only 7am in Mexico and
Texas where an additional significant percentage of our users are.
