Two possibilities come to mind. First,
might this file have a huge collection of documents in it? These
carry over through merges, so sometimes they build up. You can use
Utilities>Data File Comments to see what is there and the DROP DOCUMENTS
command to get rid of them.
Another possibility is that you have
a huge collection of value labels, even if they are not being used.

long processing time for PASW file
Dear listserv members;
I’m working on a series of datasets that
only has about 500 variables and 1000 cases in each. The files are
all really large for the content (36mb to 40mb), and when I try to process
them (get the file, merge the files, run restructuring), they are so slow
that my computer can’t finish processing them, and it seems to take all
of my processing memory (3GB). I don’t think it’s a file size problem
because I handle much larger (from a different study) datasets and it usually
takes only seconds. Could someone help me understand what’s wrong
with these files, and if there are ways to make the files workable?
