Hello Patrick,
I think the following will help you.
1) Try to find an image with the smallest size, when unzipped. Try to use
lower end routers for the Backbones
2) Use mmap=false (Really Speeds things up if you have physical memory f
atleast 2 GB)
3) Use GhostIOS feature
4) Find the correct idlepc value. Ideally, when the router instance has
settled down, your cpu should be between 6 - 15 % after applying the idlepc
value
5) Dynamips used to crash regularly . So I am using 7 instances now !!! Works
for me :)
Hope this helps.
Cheers,
Ranjith

like molasses going uphill in January. The CPU stays pegged at 100% and there
is still about 125MB of RAM free. I can run a browser and wordpad on the
laptop without much pain, but when I telnet to the routers (from another
