GNS3 Kills my system
I have been a user of Dynamips/GNS3 for several years now and I canít imagine what I would do without it. I use it for doing Proof Of Concept work and for Studying. Recently I have been throwing more and more Labs together to help me study Service Provider topics. I was getting frustrated when firing up six or seven routers and my system coming to a standstill, worse still spending ages configuring idle PC values.
The PC I am using is a HP ML110 Xeon Dual Core 4GB of memory running Windows 7 x64, so its no slouch!
I remember a few year back I got a process scheduling freebie from a HP partner which did a great job of keeping Dynamips in check, so I did some searching but could not find that product, plus it costs money, but during my searching I stumbled upon Process Lasso.(http://www.bitsum.com/prolasso.php). I have configured Process Lasso as following on my GNS3 system. (I still use the free version as it meets my GNS3 needs)
Options – >Configure Default Priorities ñ> setup dynamips-wxp.exe as below normal
This ensures my system only runs at 95% CPU usage and the system is OK for mouse and keyboard input. When I am running GNS3 I tend to dedicate the system to this and I would not be running anything else like email or other surplus programs.
If you use GNS3 then I recommend trying Process Lasso to help keep you system responsive. As my labs grow bigger I will personally get a better feel for how Process Lasso performs, hopefully not to the detriment of Dynamips. Good luck with your GNS3 labs.
