## Usage Details
### `/tmp` as tmpfs
For every processed batch, the node builds a temporary exit tree in a key-value
DB stored in `/tmp`. It is highly recommended that `/tmp` is mounted as a RAM
file system in production to avoid unecessary reads an writes to disk. This
can be done by mounting `/tmp` as tmpfs; for example, by having this line in
`/etc/fstab`:
```
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0
```
