Drastically decreasing CPU load in Dynamips

Running Dynamips takes a lot of CPU and memory and running a full CCIE topology on a Windows machine can be tough. I do a lot of studying on my commute to my job and I run some smaller labs

Multicast session booked for tonight

Going to do a rack rental tonight since I’m going to do multicast labs. From what I’ve heard Dynamips has some issues with multicast, not sure if it still has issues but I’ll do a rack rental to not spend
