Um, did it occur to you that after you emerge --sync'ed yesterday and ran |
15 |
update-eix that your portage tree is now very up to date and your eix cache |
16 |
is hot? |

|
18 |
Therefore successive runs will naturally be much quicker? And that yesterday |
19 |
was xmas day, a day most likely to involve very few if any portage updates? |
20 |
Or that emerge --sync could easily speed up simply because you had more |
21 |
bandwidth? |

|

Your speed-ups likely have very little to do with your filesystem. |
