Excel Macro, slow performance on terminal server...

[Lars Gaarde]

I'm having some trouble with a Excel macro, which transfers data from
one worksheet to another in the same workbook.

The macro is embedded in the workbook.

It is a rather large workbook with several, big worksheets.

On my own PC i open 10 copies of the same workbook and run the macro
it takes less than 1 second (Excel 2003)
If i open 20 workbooks it still takes less than a second.

On a terminal server, where i am the only user i open 10 copies of the
same workbook and run the macro it takes less than 1 second (Excel
2003)
If i open 20 workbooks it still takes less than a second.

No problem so far.

But on another terminal server (Excel 2003), the macro just runs
slower and slower the more workbooks i open.

For example:
- 1 workbook, execution time less than 1 second as expected.
- 5 workbooks, execution time around 3 seconds
- 10 workbooks, execution time around 9 seconds
- 20 workbooks, execution time around 23 seconds

If i log in locally on this terminalserver performance is fast even
with 20 workbooks as i would expect.

Does anyone have any idea what's going on?
Why is the second terminal slowing down so dramatically?

A copy of the Workbook can be found at:
http://home19.inet.tele.dk/skankkid/slow_ts.zip

The Macro in question is module1.WriteToTablesOut.

I don't think that it is the macro itself which is the problem, i
think it is some setting in either Excel or on the terminalserver.

Any ideas??

This is the macro itself:

Check the memory usege when you run on both servers. the slowerr server
probably is doing a lot of memory swapping beause it doesn't have enough
memory to run that many copies of the program.

 

[Lars Gaarde]

Unfortunately this is not the case.

We are still in the test phase and i am the only one using the server,
The server has 2GB RAM and there is loads of free physical memory when
running.

It doesn't matter how much memory is availabble, it matters how much is
assigned to the users.

 

[Lars Gaarde]

OK i didn't realise that.

I'll look into it and check if it helps.
