I'm working on a big Org file on a slow machine, so I set org-export-babel-evaluate to nil so exporting to PDF just generates the file from what's in the buffer, without doing any calculating.
Actually it does a lot LESS than that. The docstring notes that: "When set to nil no code will be evaluated as part of the export process and no header argumentss will be obeyed." and advises: "Users who wish to avoid evaluating code on export should use the header argument ‘:eval never-export’." which sounds like what you wanted.
