Hi, I attached herewith an interesting comparison between Harbour and xHarbour performance. Application is a Window GUI. The states are as of when 50 MDI Windows are opened, and when application exit.
The report says that xHarbour consumed memory twice of that of Harbour.
But an interesting value can be noted when application exit,where
xHarbour releases memory a bit better.
