- 1GB RAM + 3GB of swap is the absolute minimum but we strongly **advise against** this amount of memory. See the [unicorn worker section below](#unicorn-workers) for more advice.
- 2GB RAM + 2GB swap supports up to 100 users but it will be very slow
-**4GB RAM** is the recommended memory size for any installation and supports up to 100 users
-**4GB RAM** is the minimum recommended memory size for any installation and supports up to 100 users
- 8GB RAM is recommended for production installations, and supports up to 1,000 users
