Hello, |

I am using zfs for a while now. I am not using it for / but for /var and my |
4 |
media collection. PORTDIR is /var/portage so portage files are on zfs too. |

|

This resulted in portage being incredible slow. eix-sync took ages, emerge - |

auv world gave you enought time to prepare a meal. And eat it. |

Until I turned off readahead. |

Dear Gents, if you are trying out zfs, make sure you turn off readahead for |
12 |
your zfs disks. |

|
14 |
On a related note: increase readahead for your none-zfs SSDs. |

|

And make sure the no-op io-scheduler is used for them all. |
