Fire some heavy working SQL statements - they should suck up more memory when not restricted. But setting memory as low as possible probably will be detrimental - even FPD would try to run the base and not the extended version on 256 KB! And compared to the old engines vfp needs more memory. I have integrated calls to check for such as memory and workingsetsize into the routines of my logging/measuring "fwk" which are called not too often and give some indication on memeory usage in long running apps.
