My .sav file is 430,000 KB, so I can't show it to you.
After I just open the file and then click on 'VIEW', I 
get (Non Responding). I have to wait for every little 
thing, never mind command syntax.

I would like to respond to your message pointwise:

a) I had neverinstalled PSPP on my computer before last week,  
when I installed version 10.2. Then, as it was very slow, I uninstalled 
the whole thing. Later I installed PSPP version 10.1.

These are both from the same build generation. So this is no problem.

b) My hardware. It had recently been reformatted as there had been a problem
(I can't remember what it was due to). I also installed PSPP on my daughter's 
computer as she needs to use PSPP. The performance is about the same 
although mine is a Toshiba and hers is a Compaq. Both are at least 6 years old. 

c) Other programs on the computers that greatly slow things down? Well, there is 
Skype, WinZip, and Escan. I have had the occasion to shut those off. However 
I use Task Manager I find that only System Idle Process is competing with PPSP. 
finding that Chrome was interfering I shut that off. What does the competition with
System Idle Process mean and can I do anything about it? 

In general the Idle Proces means your processor is waiting for work. Together with a high memory usage, info on internet point to hardware problems with your harddisk. By increasing your workspace you might reduce the harddisk usage and get around this. 
Without the .sav file you use and the command syntax you use I can't say more about it.

Have fun

That leaves a few unpleasant options:

a) the installation is not correct. (Maybe mixed build generations by installing versions from different build generations without removing the old version first).  Unlikely this is the problem, but you can give it a try be removing the directory where PSPP is installed, and install PSPP again (maybe a newer version but I doubt a newer version will make any difference)
b) your hardware, especially the harddisk or its driver has a problem. Is it possible to have your hardware checked? However you wrote that you already tried on another laptop (of your daughter) so this doens't look as a likely case.
c) you and your daughter have some program on your computer which greatly slows down disk IO. You could check it by testing on a clean installed PC.

Have fun

Dear Alan, Ann and Harry,

Many thanks for your inputs on my issues of slow PSPP. 
I have used the Task Manager as suggested by Alan and 
found that often there is an alternation between PSPP 
and System Idle Manager using a high percentage of memory. 
This happens when PSPP is saying (Not Responding)

My laptop has 4 GB of memory in two main memory slots, according 
to the product specification sheet. 

If I can get a chance later I will send a screenshot.

Hi Cecily

I don't think PSPP is to slow with big datasets. 500 Mb is not that big. I just think you are not working with an optimal configuration.

The tests Alan suggested would have given more info about the problem so people could give you an advice. May guess at the moment is that you should use  a bigger workspace or have a problem with your tmp files on a slow disk. The later is unlikely as I expect just 1 disk in your laptop.

Assuming you have a laptop with at least 4 Gb memory I would recommend setting your workspace to 500 Mb or more. You can do this in the syntaxeditor window with:

set WORKSPACE=524288.

You can check this with:

show ALL.

You find the syntax editor by going in PSPPIRE to the file tab and then syntax.

If you could tell the exact file you downloaded for your work people could try to find out what is going on and help you.  It would also be usefull if you could post what happens if you change your workspace settings as suggested above.

Have fun

Thank you for your helpful replies. I now understand that PSPP works fine
with smaller datasets than with the large one I am using. I think I will
to go for a trial version of SPSS.
