So I have a small topology ( 4 AS ), and I tested it on a real environment (College Lab) with Cisco routers (2000 series).
The latency from one point to another was too high when I used GNS3, the latency just spiked (100 ms), while in a real environment was lower (22 ms).
Can someone please explain the reason?
I understand GNS3 emulates routing and switching and depends on my PC especifications. (I have a intel i5 PC with 8GB RAM).
So this is the GNS3 topology, I use my own Windows loopback interface for PC1, and Ubuntu VM on PC2.
In the real environment I use 2 different PCs (and of course, different routers).
I'm testing BGP route propagation and stuff, but when I test latency (using ping and using average value) it spikes in GNS3.
Thanks in advance for your help.
