Thread: Kmail extremely slow

  1. #1

    Default Kmail extremely slow

    For years I have used Kmail without problems. I load the emails down on my file server and open them from there - this way I can check my mails from any computer in the network. It has worked without until today. I have upgraded to 13.1 (i586) KDE desktop approx. 3 weeks ago and Kmail still worked afterwards. However now, when I try to open the mail or delete mail it takes ages more than 30 minutes and Kmail is just sitting there. At the bottom right the green slider is going left and right as if indicating the programme is doing anything but nothing happens. A right click for mark message as read does not work either. However I can move the files into different folder and I can open other files from the server (no email) so the connection is not the problem. I just try to open a 3 line text email and it was 17 minutes until it opened. Any ideas how this can be solved - otherwise my email system is useless.

    So 90% of the CPU time was mysql, kmail and akonadiserver

    It is more efficient to set up an imap server (dovecot) and store emails
    there than using a file server. Then you point any mail client you use
    (or several of them) to the server and off you go. If one day you don't
    want to use kmail, just start thunderbird instead. Another day
    outlook... Whatever.

    Thanks, robin_listas, but that does not help me at the moment. I need the akonadi server since it tells kmail where the resources are stored but it seems that kmail does not work. I cannot ask kmail to open the emails and come back several hours later to check what is written since it takes so long to open the emails. I will have a look at dovecot (any links will be appreciated) but I need to get kmail working now.
    Cheers

    It could be this bug.
    Are you willing to try a patched package?

    Default Re: Kmail extremely slow

    Yes this looks at least similar to this bug but I don't know how to apply the patch which is listed there as text file. Is there a patched version (.rpm) available?

    Yes, in KDE:Release:411. Can you test that? Note that ideally, you should switch completely to that repo, as you'll have multiple dependency issues otherwise.

    Ok, building now only kdepim4 in a separate repo, will post address once it's done.

    Thanks, sumski, I presume when you say switch completely that means all KDE applications or only all of kmail?

    I mean all packages available in the repo. Which is, for KR411 repo, whole SC release. As said in last post, i'm now building kdepim4 in separate repo. The same is valid, that you should switch completely to that repo, but it will contain only a few packages.
    Address is
    Code:
    http://download.opensuse.org/repositories/home:/sumski:/kde323929/openSUSE_13.1/
    To summarize:
    Just add the repo in this post, and switch all packages to it. Forgot anything i said about KDE:Release:411 repo =)
