Re: Importing large file to PSPP hangs

[John Darrington]

PSPP should indeed be capable of handling such a file.  However please note:

1. I don't think that large files with CSV import has been thoroughly tested.  
So
   it is possible that there might be problems which nobody has until now 
noticed.

2. Obviously, when dealing with such large files it takes time to read, so I 
would
   expect the GUI to be unresponsive  until it is finished.  In fact I would 
recommend using
   the command line interface instead of the GUI, which is always going to be 
faster.
   In any case, I would estimate that for the dimensions you mention at least 
120 seconds
   will be needed, perhaps more.

3. Whilst it should work on windows, GNU/Linux is the system which is most 
thoroughly
   tested, and for which it has been optimised.


Hope this helps.

     manage such files (even larger). Any hint?
     
     I am using PSPP 0.8.2 in Windows 7 with 2 GB Ram.
