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.
