The problem with a single-level paging scheme is that it would take up too much RAM: 4G / 4K = 1M entries per process.
If each entry is 4 bytes long, that would make 4M per process, which is too much even for a desktop computer: ps -A | wc -l says that I am running 244 processes right now, so that would take around 1GB of my RAM!
For this reason, x86 developers decided to use a multi-level scheme that reduces RAM usage.
The downside of this system is that is has a slightly higher access time, as we need to access RAM more times for each translation.

This is really cool. Ciro Santilli would be tempted to participate, but his wife is not a fan, in part due to the loss of privacy of children. Maybe she is right...
Someone should implement a version of that where you can upload your privately sequenced genome and get analytics for free.
