## Practical tip for Gentoo users
1. **Find your core count**:
```bash
cores=$(nproc) ```
2. **Choose a job count**:
```bash
# If you have an SSD and >4 GB RAM
jobs=$((cores + 1))
# If you’re on an HDD or have <4 GB RAM
jobs=$((cores / 2)) ```
3. **Run it**:
```bash
emerge -j$jobs ```
You can also put this in `/etc/portage/make.conf`:
```makeconf
MAKEOPTS="-j$jobs"```
and Portage will automatically use it for all future builds.
