First Test: How Fast Is Gigabit Supposed To Be, Anyhow?

How fast is a gigabit? If you lot hear the prefix "giga" and assume i,000 megabytes, you lot might also figure that a gigabit network should deliver ane,000 megabytes per second. If this sounds like a reasonable assumption to you, y'all're not alone. Simply unfortunately, y'all're going to exist fairly disappointed.

So what is a gigabit? It is 1,000 megabits, not one,000 megabytes. There are eight $.25 in a single byte, and then let's practice the math: i,000,000,000 $.25 divided by 8 bits = 125,000,000 bytes. There are almost a one thousand thousand bytes in a megabyte, therefore a gigabit network should be capable of delivering a theoretical maximum transfer of virtually 125 MB/due south.

While 125 MB/south might not sound as impressive every bit the word gigabit, think about it: a network running at this speed should be able to theoretically transfer a gigabyte of data in a mere viii seconds. A ten GB archive could be transferred in only a minute and 20 seconds. This speed is incredible, and if you need a reference signal, simply retrieve how long it took the last fourth dimension you moved a gigabyte of information back before USB keys were as fast as they are today.

Armed with this expectation, I'll move a file over my gigabit network and bank check the speed to see how close it comes to 125 MB/s. We're non using a network of wonder machines here, but we have a real-globe dwelling house network with some older but decent technology.

Copying a 4.3 GB file from one of these PCs to another five unlike times resulted in a 35.eight MB/s average. This is only about xxx% every bit fast as a gigabit network'south theoretical ceiling of 125 MB/s.

What'due south the problem?
