I'm experiencing this on Maverick Beta. I installed the 64-bit beta of 10.10 last night with btrfs on "/" and "/home" leaving "/boot" on ext4 and now that I've gotten around to running the update manager I'm into hour 4 of the process. I first noticed the slowness when using Firefox to search for some suitable wallpaper to replace the default that looks like someone's nose bled on my screen, but this deal with the update manager takes the cake.
I have a quad-core AMD Phenom CPU with 8GB of memory and a standard 7200rpm SATA drive. I'm normally very willing to deal with bugs in an effort to help weed them out, but I get considerably better performance on a fifteen-year- old machine running WattOS. It may have been premature to include btrfs in this release. -- maverick btrfs slow install https://bugs.launchpad.net/bugs/601299 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
