A colleague recently tried to use the OpenG Variant Configuration File Library and found that the loading and saving of more complex structures was pretty slow. A little debugging quickly showed the culprit which is in the way the recursion in that library is resolved by opening a VI reference to itself to call the VI recursively. In LabVIEW 2012 and later the solution to this problem is pretty quick and painless: Just replace the Open VI Reference, Call VI by Reference and Close VI Reference by the actual VI itself. Works like a charm and loading and saving times are then pretty much in par with explicitly programmed VIs using the normal INI file routines (cutting down from 50 seconds to about 500ms for a configuration containing several hundred clustered items). Now I was wondering if there is anyone who would think that updating this library to be LabVIEW 2012 and later would be a problem?
