Which network device will improve your network performance?
- hub
- router
- bridge
I work on routers, and say "router" but any of these could improve network performance if you have a bad network. I don't know, what do you guys think?

I would say router.
Hubs did nothing than connection, bridges will transfer boardcast storm.

Improve network performance... how does a router improve network performance? It lets you access another subnet. I guess if you have a lot of routers, it can offer different routes, therefore offering some sort of load balancing to your traffic, but I doubt that this is what they are asking for. There is always the fact that routers do not pass broadcast I suppose...
A hub would only improve performance it you changed a 10mb hub for a 100mb hub, but that sounds fishy as well.
A bridge would definitely help if you have one overcrowded segment by filtering IP packets based on the mac address in the header.
I guess this question does not tell you enough to be sure about what they expect for an answer as fas as I am concerned.

The answer is a router.
A router improves network performance by isolating broadcasts in the segment, thus preventing broadcast storms, which would inevitably consume most of the bandwidth on your LAN and bring it to its knees. It also provides dedicated bandwidth to your segment.
A bridge is not the answer as a bridge works on Layer 2 (Data Link) and allows broadcasts to pass.
A hub does not filter broadcasts either because it is a Physical device on Layer 1, and simply sends requests out all of its ports. A Hub provides only shared bandwidth to the client.
Also, going from a 10MB hub to a 100MB hub will not improve LAN performance unless the NIC's on the nodes are 100MB.
