Without Context

Over the weekend, I tested the capabilities of my newly operating LAN.  I read an article on lifehacker about a program designed to test the speed of your home network.  This article basically shouted “try me.”  And so I did.

While my LAN should theoretically be gigabit in speed, it has been almost impossible for me to find what exactly gigabit is.  The only absolute I can find is that the term gigabit means 1 billion bits.  The problem is finding the context of that.  What is truly considered a gigabit network?

This program creates a file on another computer on your network and calculates the data for you.  I sent 1 gigabyte files to my server and HTPC.  By sending this large of a file, it tests more than speed, but throughput of the network.  Every computer on my network has a gigabit network card except for my server, which has a 10/100 network card.  This is where I’m somewhat confused, as the results were somewhat similar for both machines.

What I’d really like to find out is if these numbers are “in line” with what a cat5e LAN with a gigabit router and gigabit switch should be.

While I’ve done a fair amount of “googling” this, I haven’t found any information that hits a home run.  Most of what I’ve found is out of date, or goes off on a tangent in a completely different direction.

If you happen upon this blog and are a network engineer, or knowledgeable on this subject, please let me know!
