Create precompiled header and use it to improve performance. Existing 
precompiled header can be enabled for clang model in project settings 
(Ctrl+5) / tab "Clang Settings".

Precompiled header can contain either several C++ standard library 
headers like <vector>, <string>, <algorithm>, <memory> or Qt headers 
like <QtCore>, <QtGui>. Too much headers in PCH can drop perfomance again.
