Setup is a Mac G5 running OSx with a PASCAL program running. The program is run remote desktop on various other client Macs to assist in the processing. When the monitors are plugged in to the remote desktops running the pascal programs, they run at full processing speed. However, when the monitors are unplugged from the remote desktops, they run the program at roughly 1/2 speed (consistently). Any ideas why a remote desktop (using appletalk protocol) would run slower (the processors) when the monitor is unplugged versus when it is plugged in to the remote desktop.
