Once I got my idlepc set up correctly, the CPU never EVER goes above 40% - I could probably get away with even less RAM as well, 4GB was overkill. I usually put exec-timeout 0 0 under all the console lines to keep this from happening. For some reason this seems to trigger Dynamips to go to 100% CPU. http://etherealmind.com/control-cpu-usage-in-gns3-dynamips-with-process-lasso/ Packet Pushers Weekly A podcast on Data Networking where we talk nerdy about technology, recent events, conduct interviews and more.

An expert is a man who has made all the mistakes which can be made. I couldn't even run a simple topology with 5 routers, without the CPU reaching 100%.
I'm not sure about the magic behind this, maybe someone with more expertise in Dynamips can explain this but lowering this value dramatically decreases the CPU usage. I could probably get rid of this if I allocated more memory but I only have 4 GB on my laptop.

I tried doing idel pc value, but hasn't been much of help. How many hypervisors are you running? There is a value called idlemax which is related to the famous idle-PC value.
I don't know if putting this in your .net files will work but I'm thinking if idle_max somehow gets set this should too.

I just pick up asus m5a97 motherboard with amd fx 8120 8 core and 8GB ram hope it will do the job. Very nice find! I have to shut/unshut interfaces to make this working or even sometimes to restart the whole lab. Otherwise I would recommend getting some more memory or try runnig Linux instead, it is more stable.
