The other day I went to buy a DDR stick but the shop was closed so the only solution was to sit down and fix some memory hungry applications.
These will be in 4.11:
* Fixed a bug where maildir resource would use 1 or 2GB when importing large folders.
* Fixed a bug where mixedmaildir resource would also use 1 or 2GB.
(Thanks to Martin Steigerwald for providing a a 77k e-mail folder).
* akonadiserver wasn't clearing uneeded query caches. Saved 65MB here.
