Summary: [Akonadi Nepomuk Feeder] 100% CPU waste, if I try to index mail. Product: Akonadi Version: 4.8 Platform: Chakra OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: Nepomuk Feeder Agents AssignedTo: kdepim-bugs@kde.org ReportedBy: alejandron...@gmail.com CC: vkra...@kde.org Version: 4.8 (using Devel) OS: Linux Whenever I try to index mail with KDE 4.8, CPU usage rises to 100%. This is strictly related to the mail component of akonadi_nepomuk_feeder, present in KDE 4.8 Beta 2. - The spikes are related to mail indexing. When I disable mail indexing (using the UI piece) and restart Akonadi, CPU usage returns to normal. - If I strace akonadi_nepomuk_feeder, I notice large periods of inactivity. If I strace virtuoso_t, it is locked in a FUTEX waiting loop. The symptoms look like a fixed Nepomuk bug that was fixed between KDE 4.6.0 and KDE 4.6.1. Reproducible: Always Steps to Reproduce: Let akonadi_nepomuk_feeder index some mail. Actual Results: - akonadi_nepomuk_feeder will have less than 1% of CPU, virtuoso_t will use 100% of one core. - If you strace both programs, both are waiting I don't know what (this is waste) - The actual indexing is superslow (~18 hours to index 40,000 mails) Expected Results: - When indexing, akonadi_nepomuk_feeder will have between 10 and 30% of CPU, and virtuoso_t will use between 10% and 30% of all cores (normal behaviour). - If you strace both programs, you'll notice them really working. - The actual indexing is fast (~30 minutes to index 40,000 mails). -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Kdepim-bugs mailing list Kdepim-bugs@kde.org https://mail.kde.org/mailman/listinfo/kdepim-bugs
