I have 8GB in this laptop (not expandable) and Chromium is currently |

swapping away with -j4. With -j2 it didn't so I'll try -j3 next time. |

You can set it on a per package basis: |
| 16 |
|
| 17 |
% cat /etc/portage/package.env/chromium |
| 18 |
www-client/chromium disk-tmpdir.conf j3.conf |
| 19 |
|
| 20 |
% cat /etc/portage/env/j3.conf |
| 21 |
MAKEOPTS="-j3" |
| 22 |
|
| 23 |
% cat /etc/portage/env/disk-tmpdir.conf |
| 24 |
PORTAGE_TMPDIR="/mnt/scratch" |
| 25 |
|
| 26 |
The last one is needed because TMPDIR is on a tmpfs normally. |
