Regression
Yes
Occlusion Culling appears to be slower than not culling
Steps to reproduce :
- import the project attached
- open the scene
- press play and look at CPU Usage in the profiler
- select the Antigua Stadium and clear the Occlusion data
- press play again and notice the profiler
*Note :
Regression from 4.2RC4, before clearing the data the CPU usage was lower that it is in 4.3.

We're having CPU spikes in all platforms (PC/PS4/XB1). 5.0.1 and 5.0.3

We are also seeing Camera.Render->Culling->SceneCulling->WaitingForJob stalling once every couple of seconds using 5.0.1 (the stalls are for 10-16 seconds).

Still not fixed. There is a thread about the issue here- http://forum.unity3d.com/threads/occlusion-culling-cpu-spike-in-profiler.314978/

This is not fixed in Unity5.0.0f4
Furthermore: enabling occlusion culling introduces heavy spikes in the rendering performance.
More specifically the function from profiler:
Camera.Render->Culling->SceneCulling->WaitingForJob stalls the CPU on these spikes massively.
