Valentin, thank you for your report. It is about a version of KMail which uses
Nepomuk and is unmaintained. Thus closing. If you still see performance issues
please open new reports. But please follow the following guide lines to avoid
unnecessary work for the developers:

- Ideally test with KDEPIM and Akonadi 15.08. It contains some performance
improvements like the binary protocol.

- Otherwise at least use KDEPIM 4.14.10 and newest Akonadi 1.13 you can get as
it already contains some performance improvements.

- If you can wait, please retest with KDEPIM and Akonadi 15.12 once they become
available for you. Akonadi 15.12 will contain *massive* performance
improvements implemented by Dan due to new database indexes, optimized queries
and leveled file_db directory. All of these are in master already, so if you
dare use kdesrc-build to compile KF5, kdepim and kdepim-runtime. I am using
this currently and it basically moves the bottleneck to KMail (slow threading
for example). It is a *huge* improvement.

Thank you and greetings from KDE Randa Meetings,
Martin

Maybe this bug report is the best guess for this error.

Km,ail2 4.14 waits endlessly to retrieve the content of a folder. I remember
that this was a bug before. I could not find the bug report.  It seems that the
bug is back again after the update from today / yesterday it is back again.

The problem just returned, without any aparent explanation (I did not touched
my system configuration, nor recompiled KDE). Here is the output I can see in
konsole after issuing akonadictl start and trying to navigate my folders
under kontact:


Error during executing query UPDATE PimItemTable, CollectionPimItemRelation
SET atime = :0 WHERE ( CollectionPimItemRelation.Collection_id = :1 AND (
CollectionPimItemRelation.PimItem_id = PimItemTable.id ) ) :  Lock wait

Meanwhile I setup a fresh new home folder, withour any settings. The old home
folder was renamed, then I opened a fresh-new KDE session. I configured my
accounts and folders but the problem still reproduces. How can I help to sort
this annoying thing out?

For the moment, here is a workaround, using konsole:
akonadictl stop # this instantly unlocks message retrieval and it show it, then
kmail gets disabled
akonadictl start # to resume kmail

I have a similar problem with kde 4.10.3
sometimes it get stuck with Retrieving folder contents message for several
minutes before displaying the message.
by the way, I have tried to manually open the mbox file of a new message that
was stuck in kmail, and the file opened without a problem... so, no problem
accessing the file.

I can confirm this. I have a mailbox with 10+ thousand mails inside. It took
some time to open the mailbox when the account is first setup, but when this is
done, I got stuck into this bug. 

When I select a message (ie 10 meg message) to display contents, the preview
pane stays displaying Retrieving Folder Contents... Please wait. if you wait
for like 1-4 minutes, the message displays and consequent displays of this
message is now fast. 

Note that this is an IMAP (Dovecot) server installed locally. It's super fast
in Thunderbird. So no idea why it takes minutes to open a message.

I filed the sale same report on bug #20.

Note: Disabling nepomuk email searching greatly increased the speed.
