Screen capture showing continous writes and slow read
This behaviou have ended, after more than 48 hours, kmail2 is now responsible.
Was there some indexing / database update going on silently?
This sounds like a possible dupe of bug 290393 Ohh, had forgot about this one (was me, new report my wife) Crash and slow operation in bug 326612 This bug has only been reported for versions older than KDEPIM 4.14 (at most akonadi-1.3). Can anyone tell if this bug still present? If noone confirms this bug for a recent version of akonadi (part of KDE Applications 15.08 or later), it gets closed in about three months. Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input. |
Version: 4.7 OS: Linux My kmail2 is very unresponsive - klicking on an email to show causes long waits. Up to minutes. Only related reason I can notice is that akonadi_nepomuk_email_feeder continously writes to agent_config_akonadi_nepomuk_email_feeder_changes.dat (about 50 MB/s) When trying to open mails it also reads but at a very slow rate about 5 kB/s Viewing mbox files is faster than maildir (maildir is unusable slow - minutes or ever...) Yes, I do have LOTS of folders with LOTS of mails... Kmail1 was able to handle it!
