We limited parallelization to 6 processes in October 2024
(9c0dc48162
), as that provided the
best result at the time.
However, we have a lot more specs now than we did then. According
to my testing, 10 processes now provides the best result.
For `rake frozen_spec`:
```
6 processes: 19.378s
8 processes: 17.878s
10 processes: 16.527s
12 processes: 16.721s
```
If your CPU has more than 6 logical processors, you will need to
run `rake setup_database[test,true]` to create the additional
databases, otherwise the specs will fail trying to access a database
that doesn't exist.
