Anita,

It doesn't feel that way.  Access works very well for what it does.

>A form will open fast if designed well.

You are right there.  You can grind everything to a halt by trying to use
bound forms pulling tens of thousands of records.  I had to go to the
"single record" thing for this form, but it worked and worked well.

>You can keep throwing hardware at Access applications to will make them
perform faster. The real trick is to get your database to perform fast
regardless.

That is just a silly thing to say.  Try getting a modern real database
running on an old 100 mhz machine with 64 meg.  You have to face facts and
the facts are that the machine makes the difference.  A modern machine can
be had for peanuts from Dell.  If the business owner is complaining that his
Celeron 1ghz machines running 256 megs of ram, windows 98 and Access 2000 is
running slow.... My only response will be... "and your point is?"

I use a framework which makes it very easy for me to do things like time
form openings and log what machine is doing the opening.  I showed my client
that his users complaining about slow databases were ALL on slow machines.
And yep, he is buying new modern "workstations", a few a month, to get rid
of the old junk he was running with.  And the users have quit complaining.

Sorry, facts is facts.  You can index till the cows come home but that is
never going to fly on ancient hardware.  Now, you can certainly move the
whole shooting match to a modern server running Windows server 2003 and SQl
Server and pay through the nose for that machine, OS and SQL Server, and
then pay through the nose for SQL Server and OS notworking experts.  That is
certainly an option.  Or you can update your workstations for less money and
have good performance for many (MANY) more than 10-12 users.  

And no, I am not arguing that an MDB is the solution for hundreds of users
but 10-12 users?  C'mon!

John,
My comments in line:

 Errrrr!  Wrong answer.

I have a database with 25 users in the database every day.  The BE is
currently about 800 mbytes.  This BE has tables with hundreds of thousands
of records in some tables, 30K-50K records in the main tables (claimant /
claim).  I open a VERY complex tabbed form with about 20 tabs on it, with
subforms on each tab (JIT subforms).

Users on fast machines open the form in about 1.2 seconds.  Users on very
old slow machines take about 5 to 6 seconds.

A form will open fast if designed well.

Speed of the individual workstation is the single largest determinate of
acceptable speed.  A high speed processor and LOTS of memory (1 gig for
Windows XP Pro) are essential.  Moving to a 1 gbit lan made a big difference
as well (which requires a gigabit NIC in the machines as well).
