[Desktop-packages] [Bug 941673] Re: performance of accounts-daemon is very poor
The Precise Pangolin has reached end of life, so this bug will not be fixed for that release ** Changed in: accountsservice (Ubuntu Precise) Status: In Progress => Won't Fix -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to accountsservice in Ubuntu. https://bugs.launchpad.net/bugs/941673 Title: performance of accounts-daemon is very poor Status in accountsservice: Unknown Status in accountsservice package in Ubuntu: In Progress Status in accountsservice source package in Oneiric: Won't Fix Status in accountsservice source package in Precise: Won't Fix Bug description: Version 11.10 The performance of accounts-daemon is unacceptable with large password and/or group files. We have appoximately 4 users in the passwords file and 16000 lines in the group file. Having looked at the source, it appears to me the problem is that for each user is pulls from the password database (via getpwXXX) its then calls getgroups to return the users list of groups. Getgroups must make a complete pass through the group file to determine the groups for the user. When initializing this results in reading the groups file 4 times. I think a better solution is to build a inverted group file map then first time getgroups is called by reading the entire group database and building a data structure indexed by username where a users group list can by found in a single lookup. Of couse, an even better solution would be for getgroups to do that itself, but that would require much larger code changes. I tried installed nscd to see if this would make a difference but no dice. At the moment, 11.10 is unusable for us because of this problem. Hope this is all the info you need.

[Desktop-packages] [Bug 941673] Re: performance of accounts-daemon is very poor
Thank you for your bug report. This bug has been reported to the developers of the software. You can track it and make comments at https://bugs.freedesktop.org/show_bug.cgi?id=48177 ** Bug watch added: freedesktop.org Bugzilla #48177 https://bugs.freedesktop.org/show_bug.cgi?id=48177 ** Changed in: accountsservice (Ubuntu) Status: Confirmed => Triaged ** Also affects: accountsservice via https://bugs.freedesktop.org/show_bug.cgi?id=48177 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to accountsservice in Ubuntu. https://bugs.launchpad.net/bugs/941673 Title: performance of accounts-daemon is very poor Status in D-Bus interfaces for querying and manipulating user account information: Unknown Status in “accountsservice” package in Ubuntu: Triaged Bug description: Version 11.10 The performance of accounts-daemon is unacceptable with large password and/or group files. We have appoximately 4 users in the passwords file and 16000 lines in the group file. Having looked at the source, it appears to me the problem is that for each user is pulls from the password database (via getpwXXX) its then calls getgroups to return the users list of groups. Getgroups must make a complete pass through the group file to determine the groups for the user. When initializing this results in reading the groups file 4 times. I think a better solution is to build a inverted group file map then first time getgroups is called by reading the entire group database and building a data structure indexed by username where a users group list can by found in a single lookup. Of couse, an even better solution would be for getgroups to do that itself, but that would require much larger code changes. I tried installed nscd to see if this would make a difference but no dice. At the moment, 11.10 is unusable for us because of this problem. Hope this is all the info you need.

Thank you for your bug report, that seems like the sort of issues that should be discussed upstream, somebody should report a bug on https://bugs.freedesktop.org/enter_bug.cgi?product=accountsservice While the issue is an important one it's limited to some big deployments and those can probably uninstall accountsservices (lightdm will fallback if it's not sure), ideally we would work on the issue but we have limited resources and it's not on the priority list ** Changed in: accountsservice (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to accountsservice in Ubuntu. https://bugs.launchpad.net/bugs/941673 Title: performance of accounts-daemon is very poor Status in “accountsservice” package in Ubuntu: Confirmed Bug description: Version 11.10 The performance of accounts-daemon is unacceptable with large password and/or group files.
