I am writing this to see if my “Tivo To Go” transfers between my Tivo and my PC are running at the fastest possible speed. Please feel free to double check my logic and math. Did I make any mistakes? Here we go.
So, we start with the router. It has a speed capability of 100 Mbps.
Because a megabit is one million bits this means the router is capable of one hundred million bits per second. That is 100,000,000 bits per second.
How many bytes is equal to 100,000,000 bits? Well, a byte is eight bits but I am pretty sure that like modems, ethernet also requires a stop and start bit to figure out which of the eight bits are supposed to be grouped together to make up each byte. Therefore, 100,000,000 bits should equal 10,000,000 bytes. (10 million)
How many bytes does it take to make a megabyte? 1,048,576
So therefore, a 100 Mbps router can transfer 9.536 megabytes per second.
Now, twice I have downloaded to my PC from the Tivo and monitored with Tivo desktop. In 120 seconds I got 107 megabytes both times. That equals .892 megabytes per second.
If I am supposed to be getting 9.536 megabytes per second but I am only getting .892 megabyte per second then the speed is only 9.35 percent as fast as it should be.
Right away that leads me to believe that either the Tivo ethernet port is the old standard 10 Mbps or that my PC ethernet card is not connecting to the Tivo at 100 Mbps. It could even be some kind of problem with my router. Looks like I need to start checking those things out.
Is anybody else getting faster speeds than .892 megabytes per second?
Does anyone know if the Tivo uses 10 Mbps ethernet instead of 100 Mbps?
Am I missing something here?
