Re: i7 Laptops for CCIE GNS lab

Sorry I have to chime in. Yes gns3 uses a little more resources. I have it
running fine on windows vista (the worst memory hog os) using ie or narbiks
topology. At Idle it runs at 3 percent fully loaded with configs(full lab)
it is at 45 percent. I run it on a cheap amd phenom(1.86 quad) gateway that
cost 400$ from bestbuy. I found it works better with AMD chipsets. I dont
know if there is any truth to this but from experience it does. I have a
quad core (q6700 2.67)that gets killed in the same configuration about 75 80
percent cpu. I have not tried it on an I7 machine. It probably matters more
that you need to find a sweet ios and idlepc is what makes the difference.
As far as macs they suck dont waste your money!!! Just kidding my WIFE has a
mac book pro it works about the same as my cheap desktop that runs it good.
The one thing I will say is narbiks topology most of the time you are using
only 3 or 4 routers. IE I load up the full rack with the term server too.
Get a good laptop you will be ok. Like Marko said you will spend a bit of
time figuring it out. There are some good blogs. Most of the vendors are
usually happy to send you net files in them you can see what ios and idlpc
they use. HTH The one thing I found that was easier when giving my net file
out was to put the folder with the files in the root of c then edit the net
file to reflect that then when most people use it they don't have to rename
or modify the configs (Vendors hint hint not pointed at anyone just helps us
the students).
