Auto Complete (IntelliSense) extreme slow after update to 2017.1.5

i updateted to 2017.1.5 in the morning and the intellisense is extemly slow now. yesterday with 2017.1.4 it was not fine to work, but i can work. now i have to wait up to 30seconds for a simple class property in the intellisense in my typescript project, before it was close to 2 seconds because of the size of the project.

memory usage wents from 800mb to 1.5gb by the way with this update.

feels like every update makes the ide slower this year.
