Memory usage improvements for 4.11
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.
Kontact had 5 copies of all calendaring data in memory if you used summary view which accounted for 200MB with my big test .ical file.
KOrganizer grew infinitely over night under some circumstances.
KAlarm wasn't freeing editor dialogs, resulting in infinite memory usage over time.
Mysql got up to 25 MB of savings (4.12)
Also, Dan Vratil and Vishesh Handa have been working hard on performance/memory of nepomuk and akonadi.
To be continued...
