Disabling High Performance View Passing

With High Performance View Passing disabled, the calling action block must (in most cases) copy the views that are matched to the called action block's imports and exports. The views must be copied to and from the caller's structure to two new structures that correspond to the called action blocks'
W-IA (import) and W-OA (export) structures. This must occur even if the individually matched group or entity views are the same, unless there is only one view in the import or export set and the generated structures are identical. This is the more familiar method of handling views for External Action Blocks.

This result in increased CPU usage for frequently USEd action blocks, particularly if the views are not matched identically.
