You can set under Tools>>Options>>Performance and Disk the "Deallocate memory as soon as possible" check box. This will release memory earlier than LV will normally do. It will increase runtime in the case when memory is allocated and freed often during the processing of the data. In LV 7.0 under Advanced>>Data Manipulation is a function "Request Deallocation" which will release allocated memory. This way you have a more detailed control over the memory usage.
