Docker: MongoDB connection slow

I’m working on an application where I use Docker and docker-compose to orchestrate a NodeJS container running my backend and a MongoDB container for my database. Using Docker for Mac, I’ve seen drastic slowdowns when initially establishing the database connection. When I used a Linux host, everything was extremely smooth. Since Docker for Mac creates a xhyve-based virtual machine running a Linux with the Docker daemon inside, I initially thought that this is just the usual slow in-VM performance compared to running Docker natively on the host system.
