Installed sizes:

- -rwxr-xr-x 1 root root 7.2M Sep  5 15:30 /usr/bin/mongo
- -rwxr-xr-x 1 root root  13M Sep  5 15:30 /usr/bin/mongodump
- -rwxr-xr-x 1 root root  13M Sep  5 15:30 /usr/bin/mongoexport
- -rwxr-xr-x 1 root root  13M Sep  5 15:30 /usr/bin/mongoimport
- -rwxr-xr-x 1 root root  13M Sep  5 15:30 /usr/bin/mongorestore

Expect ~50% ish compression for the package itself.

Lets think about download sizes/times for end-users in this context
