Function calls always cost some overhead, so if a large number of getglobal calls are being made, the getfenv table will be a faster route. Note that for few or infrequent calls the performance gain of this method is negligible. | Function calls always cost some overhead, so if a large number of getglobal calls are being made, the getfenv table will be a faster route.
