Measured with kdecore and kdeui I see a speedup between 25 and 30 percent.

It seems to depend on the choice of headers to include and somehow on the 
code, as with Qt the speedup seems to be higher. For development it only pays 
off when primarily working on the .cpp files, otherwise you end up with more 
recompilations due to more dependencies.

However 3.4 is said to be slower than 3.3, so one probably has to substract a 
bit from that then when comparing against 3.3.
