Why is the installation of Xbox One games so slow? (from disc)
Any games from 15GB to 50GB can take anything from a few hours to the entire night to install, why?

This is due to Xbox One's install system
Instead of installing the Xbox One game completely from the disc,
it installs from the disc then when it comes to a point where DLC/Update is required it will stop reading the disc to download the require DLC/Update files.
Then when they have been downloaded and fitted into the correct place/sequence of install, disc installation starts again from where the DLC/Update data left off.
This task requires constantly switching from disc installation and downloading data, instead of doing both process' at once, it does them sequentially.
To prevent this:
Goto settings.
Then network settings.
Then press 'A' on disconnect from your network.
Now it will install the game completely from the disc.
After this re-enable your network connection and download any updates.
This is much faster than while you are connected to the Internet.
Also another possible reason for slow installs is if your hard drive is almost full.
On most modern computers we have a defragmenter which cleans up the storage so all the blocks of data is side by side instead of spread out,
I'm unsure if the Xbox One system has an automatic defragmenter within the system but if not then,
while installing games instead of going to the next available block where data can be stored it basically rummages around the blocks just to find somewhere to store itself which takes longer
