--- Comment #3 from Martin Steigerwald <ms at teamix.de> ---
I did not yet see KDE SC 4.13 packages for Debian. I will test with KDE SC 4.13
once packages become available.

For now I raised innodb_buffer_pool_size considerably (from the default low 80
MiB to 1024 MiB), but KMail seems to be totally unresponsive here at the
moment. Raising the buffer pool size on my laptop from 80 MiB to 256 MiB for a
huge POP3 account seems to have helped, but here it does not seem to have any
visible effect. Doesn't display a mail for over an hour already. With no
significant activity – neither CPU or disk I/O wise – in atop and
Akonadiconsole not showing any activity for the IMAP resource either.

I am currently using Evolution with EWS plugin which gives much better results.
Granted, it doesn't even try to synchronize folders I did not yet click on, but
maybe thats a quite sane approach. (Seems to be choosable in configuration.)
