[Bug 398870] Re: Reading Database takes too long
I'd like to remember you all dpkg/experimental is a lot faster now... from about 14sec to 3sec here. Well using the database would be about 1sec but I wouldn't recommend to a distribution to use a wrapper (just like I don't recommend installing the library in your system, not because it's unstable but because a bad user usage could lead to unexpected results for the system).

edit to my comment above - apt-get clean doesn't actually solve this problem.

For me, this solved the problem: apt-get clean This basically deletes all the downloaded .deb files (which are no longer needed after they have been installed), which has the added advantage of freeing up some disk space. -- Reading Database takes too long https://bugs.launchpad.net/bugs/398870 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 398870] Re: Reading Database takes too long
Cron work-around: a weekly cd /var/lib/dpkg mv info info.bak cp -a info.bak info rm -R info.bak to keep the directory contiguous. ReiserFS work-around: create a ReiserFS partition especially to hold /var/lib/dpkg/info. ReiserFS was specifically designed to handle zillions of tiny files in one massive directory (under the philosophy that databases mostly because filesystems aren't up to the task). As /var/lib/dpkg/info demonstrates, ext3 is having having fragmentation trouble on huge database-like directories. Short-term solution: Have the default Ubuntu installation defragment /var/lib/dpkg/info regularly Long-term solution: Have dpkg use a database instead of /var/lib/dpkg/info. I deduce that the person who specified /var/lib/dpkg/info as a massive directory of tiny files was expecting ReiserFS to become the standard filesystem. Since that's not going to happen, it's about time to use a database. -- Reading Database takes too long https://bugs.launchpad.net/bugs/398870 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 398870] Re: Reading Database takes too long
Sorry, the long-term solution does not explain why Reading database used to be fast under older versions of Ubuntu.

we should get a button to mark a comment as a viable solution. Just like graham, the first copy took ages, but the reading now takes place within 2 seconds, where it used to be 30s. Thanks!

A moment ago, I did another copy of /var/lib/dpkg/info This time it took 1 second to copy, whereas the first time took about 3 minutes.

On the Debian mailing-list this has been dicussed here http://www.mail- archive.com/debian-de...@lists.debian.org/msg245661.html. One solution that helped me a bit (just one or two seconds faster) is the following (taken from ): 1. $ sudo su 1. % for x in /var/lib/apt/lists/*Packages;do dpkg --merge-avail $x;done 2. Rebuild /info (to work against fragmentaton; for me this took +3 minutes!) % cd /var/lib/dpkg/ % cp -a info info.tmp % mv info info.orig % mv info.tmp info 3. Finally: % dpkg --clear-avail _and_ reboot (for whatever reason ...) On the mailinglist above there was also a pointer to http://people.debian.org/~seanius/dpkg-sqlite/ for a proof-of-concept sqlite powered cache, which would fix the slowness problems. -- Reading Database takes too long https://bugs.launchpad.net/bugs/398870 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

On my 4-year-old notebook on Hardy Reading database used to go fast. Now I have Core2 Duo P8600 (2,4 GHz) and on Karmic it goes slowly with steps 5%-sized, maybe 3 such steps per second.
