Hi all,

I want to ease the load on a network.

1. If i automatically close windows that are left open by user after an
amount ot time, is it going to help?

2. Is it true that a form with lots of object on it is a load on a network?

3. Is it true that using short names for database and link database will
make a difference in performance or
is it old stuff no longer true?

4. If i modify the size of long text fields (255) for shorter (40) will it
help knowing that all those fields are empty most of the time?

Possibly. Open tables are refreshed by a background process.
If you don't have any windows open, they won't have any bound
tables open, and you may reduce the background traffic.

A form bound to lots of different tables loads the
network more than a form without those bindings.

It is /probably/ no longer true. What kind of network are
you using?

No. It will have no effect except to stop you putting
longer strings into the field

Are you having any specific performance problems?

The three most common performance problems in Access 2000 or newer
are:
- LDB locking which a persistent recordset connection or an always
open bound form corrects (multiple users)
- sub datasheet Name property set to [Auto] should be [None]
- Track name AutoCorrect should be off

If the problem is for everyone when starting up the MDB then it likely
needs a decompile.

No.

Of course. But sometimes you need to have a form with a number of
combo boxes, list boxes and subforms. That's life. But even then
there are some things you can do.

Yes, this is still true but not that significant in 100 megabit
networks. Very true in slow networks such as dial up. Which you
shouldn't be running in Access anyhow.

No. Setting a different field size will make no difference in
performance. Access only uses what space it needs to anyhow.
