The next version of the Qt window manager, expected within a year, will run better on embedded systems, according to Qt Development Director Matthias Ettrich speaking at the KDE Developer's Conference.
Ettrich said Qt 4 will strive for:
- Better start-up performance
- reduced number of symbols
- less read/write data
- fewer static initilizers
- Better runtime performance
- fewer mallocs
- faster and more optimised tool classes
- reduced memory consumption
Ettrich said that a version of Qt Designer ported to Qt 4 resulted in a libqt size decrease of 5%, num relocs drop of 30%, malloc use drop of 51%, and memory use decline of 15%. Startup time declined by 18%.
Qt 4 will comprise multiple smaller libraries, too, for leaner deployments.
More detailed technical information from Ettrich's remarks is available at KDE.org.
