The best fs for emerge is tmpfs on TMP_PORTDIR. I run box with tmpfs on |
| 18 |
both /var/tmp and /tmp and happy with it -) |

For fs CPU usage is nothing, IO usage is a real problem and weak point. |

Thus, you are free to choose any fs with full journaling. ext3 allows |
| 22 |
full journaling as option, as well as ext4 and ext4 is little faster if |
| 23 |
tuned properly. JFS/XFS journals metadata only. Remember that journaling |
| 24 |
makes writes (i.e. emerge) a bit slower. |
