When I started adding hotspots to my scene I discovered that the FPS-counter in the Unity-editor dropped drastically. Before I had 70+fps (14milliseconds) and when I added 7 hotspots it dropped to around 35fps (27milliseconds). Then I tried adding 7 more hotspots and it dropped down to around 20fps (45milliseconds). The scene is pretty much empty with just a couple of doors, a floor, roof and walls.
This doesn´t feel very good, there must be something wrong or maybe it´s just when in editor that this happens? Because when I build I have constant 60fps which is maximum on my monitor so it´sprobably more.
I have a 4790k, 16gb Ram and a 970GTX so there is nothing wrong with my computer.

There are a few things going on in the Editor that might give a lower performance than builds, however. Try writing a simple script that outputs FPS to the screen and test in a build.
If you open up the Profiler when running, see if you can find spikes that might indicate what's causing the slowdown. At least this seems to be an editor-only issue.
