GNS3/Dynamips performance
Hi all,
I was going to do some experimenting on routing traffic different ways while benchmarking performance. I get very low performance when performance testing links in GNS3. iperf shows about 1,3 Mbps tops regardless of link type and generated traffic (tcp/udp, window size, parallell streams etc), even in a very simple topology with two routers. The host machine is a Retina i7 macbook pro with 16 GB RAM, the load on the machine is piratically zero. VirtualBox guests is a clean, tiny debian install. Tried on Windows 7 as well, no better luck there.
Anyone out there who care to share some iperf benchmarking results, in GNS3, so I have something to compare with?
Thanks.

sorry I forgot to mention that I always include idlepc and idlemax to my GNS3 topologies, but still I find its very slow when using macbook compared to windows.
