Review request for KDE Frameworks and Milian Wolff.


Repository: kitemmodels


Description
-------

QMetaObject::invokeMethod calls QMetaObject::indexForMethod internally,
which is rather expensive. So look up the method once, and invoke it
via QMetaMethod directly.

Diff: https://git.reviewboard.kde.org/r/122109/diff/


Testing
-------

Tested and measured with the KRFPM usage in GammaRay, saves about 5% of total application CPU cost according to callgrind.


Thanks,

Volker Krause
