            Bug ID: 329205
           Summary: Huge memory usage just for the calendar with korgac
                    and ical resource
    Classification: Unclassified
           Product: Akonadi
           Version: 4.11
          Platform: Kubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: ICal file resource
          Assignee: kdepim-bugs at kde.org
          Reporter: alexandre.bonneau at linuxfr.eu

At all time, I have 1 GiB of memory used by korganizer, korgac and
akonadi_ical_resource processes, and only 72 MiB of it is shared.

The main memory hog seems to come from a duplication between the korganizer and
korgac processes, respectively with 487 and 469 MiB used.

Here is my memory consumption using 4.11.2 :
Process | Memory | Shared memory | Virtual Memory
korganizer | 487.7 M | 31.0 M | 1.2 G
akonadi_ical_resource_1 | 5.0 M | 12.7 M | 308.4 M
akonadi_ical_resource_2 | 126.7 M | 13.5 M | 448.6 M
==> korgac | 469.0 M | 15.1 M | 1.0 G <==

The total memory usage for a single calendar is in my humble opinion far too
high (more than 1,088 GiB) for a 6.7 MiB ics file.
This is specially true for netbook users.
