Bug ID: 334206 Summary: While maildir resources synchronrizes a folder KMail blocks on switching to a different folder Classification: Unclassified Product: Akonadi Version: GIT (master) Platform: Debian unstable OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: server Assignee: kdepim-bugs@kde.org Reporter: mar...@lichtvoll.de I found that while Akonadi maildir resources synchronizes a folder certain operations in KMail are block. I found this to be the case with switching to a different folder. It takes minutes before KMail responds again. Reproducible: Always Steps to Reproduce: 1. Have a maildir resource. 2. Have a large folder. 3. Have Akonadi synchronizing it. 4. Click on a different folder in kmail. Actual Results: KMail is blocked for minutes. It just doesn´t respond to clicks while Akonadi maildir resource is 100% busy. If I kill this process KMail *immediately* responds to the last user request, but then is blocked again after Akonadi restarted the maildir resource process. Expected Results: KMail responds to user requests immediately or almost immediately. KMail´s GUI is never blocked according to the following design goal of Akonadi: Concurrent access allows background activity independent of UI client Syncing mail, calendar, addressbooks to remote servers Syncing with mobile devices Permits semantic desktop infrastructure to access PIM data Archiving Indexing Out-of-process search http://community.kde.org/KDE_PIM/Akonadi#Features I can share a collection of large folders as xz archive, including kernel-ml folder with about 220000 mails. Dan already got a copy of these from me. I/O is not the issue here. Akonadi is hogging the CPU 100%, SSDs are *not* fully ultilizes. I am tempted to raise the bug priority to more than normal, as this bug makes KMail unusable for minutes. I am currently using Akonadi git 1d1969c65c10c9d3f054f6dafb0f5a2a97d48281. -- 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
