Access Databases running extremely slow.

I have noticed lately that several access databases that i've been working on have been becoming rather slow.  Is there any way to speed them up?

I've tried defragging the computer.
I've tried disk cleanup.
I've tried clearing the cookies on IE.

and i'm out of ideas.

Oh and since it's an office computer i don't have the authorization to do hardware upgrades, nor to request that they be done.

You could check to see if these databases have good indexes on them.  How big are these databases (size and number of records)?

Have you done a Compact & Repair on the databases?

You might also have your network folks check your routers.  I'm not systems guy, so I may get the syntax wrong, but in my last job, we had a router somehow get switched from 100M to 10M speed, and with 50 people sharing the bandwidth, things really started to crawl.

at the moment they are in the design stage so there is no records.  The only tables with records at this point are being used as the source of lookup fields.
No i haven't done a compact & repair, how do i do that?

The tables that contain the source of the Lookup fields don't have more than 70 records each and no more than 3 fields per record.  There are no attachment fields in any database.

If there are no records - how do you know the database is slow?

You mention that the application is split.  Is the front-end on your PC, or the network?

Ok I have 2 sides to the DB
The Master which contains only tables
and the local wich contains everything else.
The local and master are 2 separate accdb files but are linked together.
I double click the local DB, open up the switchboard.
I try to click a button on the switchboard that is supposed to open one of the forms in the DB and it takes 5 min to open when previously it took a matter of seconds.
Am i not correct to say that it's slow.

Highfive Gives IT Their Time Back

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

Also due to regulations set by our IT department I get a security warning every time the database opens.  Where I have to click Options >> Enable this Content >> OK.
I know that it's possible to setup a trust in the trust center but the IT dept. won't let us do that.
Could that slow us down too?

one more thing every single button on the switch board and in the forms is macro-oriented.

also when i'm in design view working on the master i notice that there's another issue.  If i try to use the lookup wizard on a field it shows me the hourglass for a good 15 min if not more.

This clearly sounds like a network issue.  If you have *no* records, then there are system problems that your IT Dept needs to look into.

Have you same issue only on your computer or in other too? There could be problem with local computer. Try to copy big files from network and from one folder to other. If there will be problems, ask you IT department for help.

Have you run through these Microsoft performance tips for a split database?
http://support.microsoft.com/kb/889588

Have you tried unsplitting the databases to see if performance improves?  There are many documented examples of split database performance issues.

Also, have you tried moving the databases to your local machine to see if performance improves?  This will eliminate the network as your performance problem.

Sounds like a network issue.
When I develop Access apps I put the back-end (tables) on the server.  The front-end (application) gets copied to each user's PC.  That's the fastest way to run it (and the safest).   I have version control so if I enhance the front-end, I change a PUBLIC variable within the front-end - and then change a .txt file on the shared server folder.  Upon startup, the system compares these 2 values and if they don't match - I force a download of the latest version.

"No i haven't done a compact & repair, how do i do that?"

Well, with almost no records, not likely to do much ... BUT ... just in case:

Open an mdb.
Tools>>Database Utilities >> Compact & Repair.
