Weird FPS and CPU usage with Unity5

Since I've started using Unity5 I'm periodically getting some weird effects in CPU usage and FPS (frames per second).

I sometimes get high CPU usage notifications. Up to 100% according to task manager and a frame rate of 20-25 FPS. Now I can save my scene/project, close unity and when I restart unity I get no CPU warnings and a frame rate of 65-75 FPS (unity 4.6 always ran somewhere around this figure)

Even if I don't make any changes at all to my game/project but just open and close unity I can get these vastly different results each time.

Does Unity5 suffer from memory leakage? or is there another explanation for this issue.

???

Do you have continuous light backing enabled? Thats running in the background and may take up a loot of CPU time.

took a couple of attempts to get the result but here are the stats from exactly the same game/project build. No changes at all, just closed and reopened unity.

This is beco$$anonymous$$g a real PITA now. Just started work on a new scene and as such there is obviously far less items in this scene. However I keep getting High CPU Usage warnings for 'Unity Job Process'. I mean.. really ! $$anonymous$$y system may not be top end, but its certainly no old fart either. I have no problems playing any game on maximum settings but Unity 5 is killing my machine.
