Loading time increases with every time I press play

I'm not sure if this is a Unity issue or my PC slowly decaying in front of me. Everytime I press play, Unity takes a bit longer to actually "play". When I restart Unity, it loads up in an instant but then it stats to become slower and slower. This feels like a memory issue. It's very hard to work efficiently like that. Maybe someone
out there can help me with that.


I'm using Unity 2017.4.2f2.

 

check editor.log if theres anything https://docs.unity3d.com/Manual/LogFiles.html
or try profiling the editor, from Window / Profiler
