[Bug 601299] Re: maverick btrfs slow install
There are a number of factors in play here. btrfs is not production ready in the Maverick kernels, it is slow in general and very slow in the face of an fsync centric load. Btrfs was enabled in the installer as an experimental feature, as a technology preview, and as such it is not likely anyone is going to work to backport any performance fixes to Maverick. For Natty we are expecting some direct improvements from layout improvements, and from upstream fixes.

I did a related benchmark on a Debian unstable system (with dpkg 1.15.8.5 and linux-image-2.6.35-trunk-amd64) and an ext3/4 file system. Here were the results: This affects my ext3/4 filesystem (ext3 mounted with the ext4 driver, but none of the advanced ext4 features enabled) as well.

Ok, 10.10 is just released and I downloaded it. I tried installing it with / on btrfs and after 5 hours the install was at 75%. This is on a AMD Turion II Dual Core M500 with 6 GB. My / was 550 GB. It's a shame this issue wasn't resolved before releasing Maverick and this will hurt BTRFS adoption for sure. IMHO this should never had been released in this fashion since this bug was already reported in the Alpha release. Why bother with alpha and beta releases when isssues like this are not resolved.

I don't think it is just btrfs. I am using XFS on top of software raid 1 in Maverick, and if I am doing any disk I/O (e.g. a big copy) dpkg will take a very long time to unpack. Stopping the disk I/O often won't solve the problem (maybe patience will).

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.

[Bug 601299] Re: maverick btrfs slow install
On a btrfs-related note, the developers have only just realised that it might be worth advising btrfs users of the following caveat (see the wiki at https://btrfs.wiki.kernel.org/index.php/Main_Page): Note that Btrfs does not yet have a fsck tool that can fix errors. While Btrfs is stable on a stable machine, it is currently possible to corrupt a filesystem irrecoverably if your machine crashes or loses power on disks that don't handle flush requests correctly. This will be fixed when the fsck tool is ready. ie it is ridiculously easy to lose an entire partition! @James: I can confirm what Conn said in comment #9: when I tried the Maverick btrfs install in a VirtualBox environment, it ran chronically slowly until I enabled the host disk cache, and now it runs at normal speed. -- 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

[Bug 601299] Re: maverick btrfs slow install
James, In comment #6 you mentioned that you experience no btrfs slowdowns in a virtualized environment. That's probably because btrfs is running on an underlying filesystem, with a separate caching mechanism by the physical hard disk and host OS's handling of your disk. The net effect seems to mitigate whatever performance issues exist with btrfs, as opposed to what happens when used directly on bare metal. -- 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

I've found reference to what I believe is this issue on the BTRFS mailing list... it seems that there may be a significant performance regression in certain configurations, but Chris Mason has identified the cause, and it should be patched... the issue for many of us of course is that Maverick is frozen on the 2.6.35 kernel and so if this is the issue, we may not see a fix before 2.6.36 unless canonical backport it, which may not happen since it's not officially supported... :( I have posted a link to this bug to the btrfs mailing list thread to confirm that the problem is not just theoretical:- -- 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

I can confirm the same issue; installation via the alpha 2 32bit alternate media takes ~2 hours when installing to a btrfs partition, compared to ~15 minutes to ext4. I'm not sure that system specs are necessary, because I don't think this is a bug (or if it is, it should be addressed upstream).
