I also found this to be the case as I rebalanced the root filesystem of my Debian installation on this ThinkPad T520 on an Intel SSD 320. It doubled the boot time that systemd-analayze rebootet back then. apt-get dist-upgrade was noticably slower to. Thus I avoid balance unless I really need it. For migrating of /home to BTRFS RAID 1 on Intel SSD 320 + Crucial mSATA M500 SSD I did a balance to switch to RAID 1. Probably /home would be faster recreating it from scratch and restoring from backup tough. Especially MySQL based Akonadi seems to be slower than with /home on a single SSD, but that might also be due to that amount of mails in Linux kernel-ml folder raising to a high amount (and inefficiencies in Akonadi). -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
