I am working in SPSS 20 developing a dataset, and for some reason every time I try to either merge variables between two datasets or sort cases it takes ages, literally 100 cases per minute. I have had a play around and this seems to happen regardless of whether I use syntax or the menu options.
There are around 15000 cases in the files, merging one or two variables at a time. Its on a university networked computer, but I have checked my personal drive (where all the files are) and there is more than enough memory.
Any guidance would be much appreciated!
