You need atleast 2Gig RAM.

I'm a Dell fan so I'd recommend them. DELL has AMAZING DEALS at the moment
on their Inspiron notebooks. FULLY LOADED laptop with EVERYTHING
GREATEST for under a thousand.

Also, make sure you are using idle pc value. This makes most difference when
opening multiple instances.

The "idle PC" feature allows you to run a router instance without having a
100% CPU load. This implies that you can run a larger number of instances
per real machine.

To determine the "idle PC", start normally the emulator with your Cisco IOS
image, and a totally IOS empty configuration (although not mandatory, this
will give better results). When the image is fully booted, wait for the
prompt to be ready, do a "write memory" and then press "Ctrl-] + i" sequence
key after some seconds. Some statistics will be gathered during 10 seconds.
At the end, the emulator will display a list of possible values to pass to
the "idle-pc" option. You may have to try some values before finding the
good one. To check if the idle PC value is good, just boot the Cisco IOS
image, and check your CPU load when the console prompt is available. If it
is low, you have found a good value, keep it preciously.
