What are you seeing?

We see script caching not working as we hoped. For example:

Run (according to build system): 39 seconds, but Cake logs show:

Task                          Duration            
--------------------------------------------------
Setup                         00:00:00.2121813    
Prepare                       00:00:00.2494064    
UpdateNuGet                   00:00:00.0003786    
RestorePackages               00:00:05.8670747    
Deploy                        00:00:01.2517940    
--------------------------------------------------
Total:                        00:00:07.5808350    

So theoretically 32 seconds can be shaved off.

I am currently adding logging to the script compilation (although this is on a much faster machine):

Without cache file:

Compilation took '00:00:01.5861141'

With cache file:

Loading script assembly from cache took '00:00:00.0036443'

I think this would be a nice addition to always log to the output window (I think people want to see this).

Will add more tracings and update this ticket.
