I need to do a latency test between two machines, basically a ping-pong packet test. I wonder what is the fastest connection I can have between those two machines. I imagine my options are:
- Ethernet through a router, but then my bottleneck will probably be the router unless you can recommend me a cheap and very fast router
- Ethernet through a switch, but then my bottleneck will probably be the switch unless you can recommend me a cheap and very fast switch
- Some kind of NIC-to-NIC connection using an ethernet cable
- Infiniband (that would be awesome but I don't think I will be able to do that at home due to its cost)
