I'm loading a data set with about 5 million records and a few hundred
columns. While loading, my system never uses more than 20% of available RAM
or CPU and never more than 2% of disk. (I've done it several times because
I keep running into minor errors in my script.) Is there a recommended way
to use more of my capacity to speed up the process? My paging file is at
the recommended/auto setting.Optimisation issues like this are hard to answer, because so much depends on the individual circumstances. First some questions: * How long does it take you to load such a dataset? (how many minutes?) * From whence comes that dataset? From a .sav file or something else? * Are your variable string variables or are they numeric? Right now I can make these suggestions (but can't promise any will work): * Use a unix based system instead of windows. (pspp is designed for GNU/Linux so it is always going to work better there). Serious use is never going to be optimal on windows. * Try increasing the "WORKSPACE" setting (see Section 16.2 of the manual) This will mean it should use more of your 16GB of RAM. * If you are using psppire (the GUI), then don't. Instead start pspp from a terminal and run it in the conventional way. (A lot of processing is wasted generating pretty screen graphics). I'd be interested to see how these work for you. J'
