    How to drastically lower CPU Utilization when using GNS3

    Hello boys and girls,

    I know that many of us have issues with our PC's CPU pegging out when we run GNS, but I think that I have found a solution to drastically lower load on the CPU.

    I ran across a site that provided info on how to drop your PC's CPU load while running GNS by editing your .net file. If you use the "idlemax" command in conjunction with changing the "idlepc" value, you will definitely notice the difference. It dropped my processes by a huge amount with the full INE lab
    running. Each dynamips process is now running under 10%!!!

    Check it out for yourself. HTHs!!! Big Smile
