QtCreator with boost library is very slow

[Scope]

You have the same insights?
I include only a few headers from boost ( asio, signals2 ) and when I click '.' I must wait few seconds for list of methods, types etc.
The same when I want to switch between header and source files. Without boost it works very fast but with boost it works horrible.

It is normal? How I can speed up QtCreator when I need use boost?

Boost 1.60.0, Qt 5.5.1
I have 4 cores, 8GB RAM, Windows 7 64-bit.

Are you working on a qmake based project or a generic one?
