Just to give an idea of the speed of Specctra and Electra routers. My friend did a full size PC Interface Card with a 32-bit CPU, RAM etc. on a 4 layer board. It took him in the order 60 hours to fully route the PCB. Specctra routed the same board with the same design rules in less than 2 minutes. The one Demo PCB in Protal/Altium which the Protel/Altium router routes on 8 layers in about 3 hours, Specctra routes in 2 layers using the same clearances and track widths in less than 5 minutes.
