GNS3: Save a little memory with VPSC
This tip was emailed to me and seems pretty sweet (haven't tested it). Check out this link:
Rather than eating up resources using routers as hosts in GNS3, you can use a Virtual PC Simulator (VPSC) that can ping, traceroute, get a DHCP address, etc...
While this is good in theory, I'm curious how difficult it is to roll this into the Windows version. With memory becoming a cheap commodity, it's just too easy to drag another router on the GNS3 landscape.
