I have the same problem, system slowdown and a very long updates. I have the measurement for speed-dreams package 1.4.0 installed from command line (sudo dpkg -i speed*) for Ubuntu 9.10 and 10.04. Both installations are on the same machine, same HD (different partitions, ext4 for 10.04, ext3 fot 9.10), and speed-dreams files (~320MB) are on a another HD.

[Bug 537241] Re: My computer updates are very slow since latest dpkg update
I guess this bug also causes the massive slow-down during the Ubuntu installation (compared to earlier Ubuntu versions). I had already several reports about the standard installation hanging at 95 % (or whatever other percentage). At this point the dpkg database is built/updated/whatever. The installation does not really hang, but depending on how slow your disk is, this step can take up to 15 minutes (perhaps even longer on really old computers). This also affects the alternate installation, but in a somewhat lesser degree (according to my own experiences). When Ubuntu 10.04 has nearly achieved a boot time of 10 seconds (it's more like 20 seconds on my computers, but it really boots much faster than before), installation time has almost quadrupled :-( One step forwards here, one step backwards there -- My computer updates are very slow since latest dpkg update https://bugs.launchpad.net/bugs/537241 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 537241] Re: My computer updates are very slow since latest dpkg update
My concern is not related to the time it takes, but the disk activity and loss of responsiveness during package updates: it's all about user perception. When the change has been introduced, I noticed a lot of writes to the disk with a lot of time spent in syscall (quite normal for frequent fsync). My immediate reaction was to suspect that the hard drive of upcoming failure, since it behaved like it had difficulties to read or write (and then I found this bug report).

[Bug 537241] Re: My computer updates are very slow since latest dpkg update
Philip, the 247 reporters of the original report (#512096) didn't intentionally break their system. I suppose that most of them don't even know what data=writeback is. To reproduce it on a fresh lucid setup: - to be sure that the right mount options are set add auto_da_alloc,data=ordered to the ext4 line in fstab and remount. - install a previous version of dpkg (e.g http://archive.ubuntu.com/ubuntu/pool/main/d/dpkg/dpkg_1.15.4ubuntu2_i386.deb) - simulate a crash: $ apt-get install bsdgames ; sleep 5; echo b /proc/sysrq-trigger When your system as rebooted, see all those 0 bytes files: $ ls -l /var/lib/dpkg/info/bsdgames.* $ ls -ld $( dpkg -L bsdgames ) auto_da_alloc doesn't even detect the replace via rename situation (in fact it does, but only in the simplest cases) Once the files in /var/lib/dpkg/info/ and /var/lib/dpkg are corrupted there is no other to recover than running some manual operations. Which are like black magic to the common user who generally end up with a complete reinstall. Users can complain about performance but won't complain about loosing their data. This situation is not specific to dpkg. Try : $ ar x dpkg_1.15.4ubuntu2_i386.deb; sleep 5; echo b /proc/sysrq-trigger it will leave 0 bytes files too. It's not the place to discuss about it since this report is about performance, but I don't think the solution is to add fsyncs to all the applications around and it is not realistic. The solution is to fix ext4 itself. To draw a parallel, there is no single database engine leaving empty rows when a transaction failed.

[Bug 537241] Re: My computer updates are very slow since latest dpkg update
I believe that the failure only occurs when you intentionally *BREAK* your filesystem by using data=writeback, so a factor of two performance penalty for a protection that is unneeded on the default data=ordered mode is unacceptable to me. At the very least the syncing should only be done if data=writeback is detected, or the syncing and renaming should be delayed until after all packages are unpacked if possible, so that it is only done once. Leaving this in for lucid release to be on the safe side is probably the right thing to do at this point, but this should be revisited later. -- My computer updates are very slow since latest dpkg update https://bugs.launchpad.net/bugs/537241 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 537241] Re: My computer updates are very slow since latest dpkg update
Reopening this bug since -ubuntu4 has reintroduced it. It may not be as bad as before, since cjwatson said on irc that syncing is now only performed after unpacking all files in a single package, but I just tested upgrading beta 2 to current and the time to upgrade went from 6m21s to 11m15s. To test I made a clean install of beta 2 to a new lv on my ssd, booted into the new install, ran apt-get update ; apt-get upgrade -d to download all the files needed. Then I booted back to my main install and made a backup of the test volume using dd. Booted back into test system and locked the version of dpkg to -ubuntu3 and ran a time apt-get upgrade -y. I then booted my main system and restored the dd backup, booted back into the test volume, and first upgraded dpkg to -ubuntu4, then again ran time apt-get upgrade -y. It seems that this fix may be to solve a problem caused by people using data=writeback mount option on ext4, which is documented to be unsafe, and comes at a hefty cost to upgrade a number of packages at once. Because of this I feel this fix should be reverted. ** Changed in: dpkg (Ubuntu Lucid) Status: Fix Released = Triaged -- My computer updates are very slow since latest dpkg update https://bugs.launchpad.net/bugs/537241 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

Thanks. That was expected because few fsync have been added to prevent data loss when the system crashes during an upgrade (bug 512096) Are you able to compare the performances of the latest version of dpkg with the previous version? ** Changed in: dpkg (Ubuntu) Status: New = Confirmed -- My computer updates are very slow since latest dpkg update https://bugs.launchpad.net/bugs/537241 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 537241] Re: My computer updates are very slow since latest dpkg update
not really, unless you give me a link to the previous version package and a list of packages which could make a good benchmark. In that last case I would be happy to help testing and comparing. -- My computer updates are very slow since latest dpkg update https://bugs.launchpad.net/bugs/537241 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 suppose in that case that trying reinstalling packages could make the benchmark, and that it won't matter reinstall a package which the previous dpkg package. -- My computer updates are very slow since latest dpkg update https://bugs.launchpad.net/bugs/537241 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 537241] Re: My computer updates are very slow since latest dpkg update
I got the dpkg packages (thanks archive.u.com not delete previous versions too fast !) but if you want a reliable benchmarking test I need a list of packages to reinstall (maybe a kernel, kernel headers and packages with triggers ? Seems to me they were the slowest ones). I'm waiting for your advice on this.

[Bug 537241] Re: My computer updates are very slow since latest dpkg update
I use to play with the texlive package. They are non critical, and some of them are shipping a large number of files. texlive-latex-extra-doc (+8k files) texlive-generic-recommended (~ 300 files and install-info and tex-common triggers ) hello or bsdgames are rather small but good for testing purpose. -- My computer updates are very slow since latest dpkg update https://bugs.launchpad.net/bugs/537241 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
