Memory usage improvements for 4.11

Thursday, 18 July 2013  |  sergio.martins

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...
