QtCreator code-editor very very slow

Hallo, I updated QtCreator from 3.6.1 to 4.10.0 .
What a surprise, an instantan code checker is integrated in the editor. In general this is a very good idea, but it so slow that code writing is no more possible. 1-3 seconds for one character.
Why is that so slow? What can I do ? How to disable the whole function ?
Yes its a bit taxing as it now uses a real compiler pr default.
(it also offers better completion with templates and auto keyword)
We have a thread about it
you can simply disable the plugin and use the old way.
However, normally it wont lag that much so just typing is also slow.
and then restart creator.

Hi @mrjj, thank you for you help.
Now, after round about 2 hour of testing, it works without any changings suddenly without no time lag . I dont know why - I will keep an eye on the effect.
It seems to do some sort of indexing and that can take some time.
I also experienced that suddenly it was quite fast after i left project open and getting

Yes, the code completer needs strong coffee to work properly.
