Gigabit Router

[freste]

Can someone tell me if I would benefit from a Gigabit router?
Here's my current setup (of course numbers are theoretical):
my laptop: 10/100 mbps
girlfriends laptop: 10/100 mbps
media player: 10/100 mbps
desktop used as downloader/filesharing server: gigabit
Router: 10/100 mbps
internet speed: 100 mbps

As I understand it, i can get 100 mbps out of every port on my router, correct? Am I correct to assume that, if all at the same time:
-I'm downloading something on the server
-I'm copying something from the server to my laptop
-my girlfriend is transfering pictures from her laptop to the server
-the server is copying a movie to the media player

then all those things combined can only use 100 mbit since that's all connection between router and server can support?

If so, can I assume that, even if only the server can actually get gigabit speed, switching to a gigabit router will give me 100 mbps each since the connection between router and server would be gigabit and the total used would be 400 mbps?

Am i correct with this?

Theoretically, yes.
You'll probably find out that the server is limited in speed too,
a hard disk has limits too.
You won't get 400 if the server cannot deliver more than (say) 300.
It's probably worth the investment though.

Better off investing in a 10/100/1000 Ethernet switch. Cheap, and dedicated to doing nothing but inter-LAN switching, unlike routers which tend to have very flaky switch ports and are even worse if routing traffic on different LAN's, which I'm assuming you're not doing.

Either way investing in a near-Gbps routing router should be in the mind of anyone in the market for a new router.

I had issues with Sab on my HP Microserver, it would only download at a max of around 120mbit. I have a dual connection reaching a maximum of 225mbit. I switched to NZBGet and am getting full speed now without as much CPU usage.

So bear that in mind when upgrading routers/switches. I spent a load of money, trouble shooted to death only to realise my Microserver wasn't powerful enough.

Also the thing to look at when purchasing a router is WAN-LAN throughput. Many have gigabit ports but their throughput cannot keep up with fast connections.
