What's the difference with running mongodb directly?

I found this project but I wonder,
what's the difference from running mongo with tmpfs?

docker run --name mongo --mount type=tmpfs,destination=/data/db -e MONGO_INITDB_ROOT_USERNAME=root -e MONGO_INITDB_ROOT_PASSWORD=dummy -p 27017:27017 -d mongo:4.0

Running mongo with tmpfs will get you part of the way there. This project also does things like:

• Disables journaling
• Disanble or restricts preallocation of data files where appropriate
• Disables logging output

All of these will have some impact on speed. This project is aimed to be used for a test suite or something like that where performance is important, but resilience isn't (hence disabling journaling, etc)
