Would it be good to be able to serve the same number of users<br>
while reducing resource consumption, including bandwidth, by 70%?<br>
<br>
Let's get rid of some of the noise in the data and compare just<br>
DVD versus CD. Using the NetNITCO data let's look at only the<br>
most rcent release, 5.6, and for less noise let's look at<br>
the most popular CPU, i386:<br>

CD 1 is downloaded 38% percent as often as the DVD -<br>
a significant amount. So people seem to want CDs a good<br>
portion of the time. Also interesting is that CD 6 and 7<br>
are downloaded about 1/3rd as much as CD 1. It looks like<br>
a lot of people are like me in that they do installations<br>
with only the first CD or two and don't need to download<br>
all 4 GB.<br>
<br>
That's a 70% reduction in bandwidth, time, disk io on the<br>
mirrors when they get CD #1 & #2 instead of the full DVD.<br>
Every user who is served by downloading only 2 CDs totalling<br>
1.2 GB instead of 4 GB is good for the mirrors, good for<br>
the network, and good for the users. If they are forced to<br>
download the DVD instead, that means they use three times<br>
the resources that they currently do.<br>
<br>
I don't currently run a mirror because I don't have quite<br>
enough bandwidth available, but if I were running a mirror<br>
I'd rather serve up 1.2 GB to each of those users than 4 GB.<br>
