MATLAB COM Automation Server as In-Process?

I have a python application that launches MATLAB using the Automation server:

client = win32com.client.Dispatch("matlab.application")

I'm trying to improve the performance overhead for the Get/Put/Execute commands that follow. Reading on http://www.mathworks.com.au/help/matlab/matlab_external/introduction_brd0vd4-1.html it seems to indicate that running the server as an In Process server would be something that may improve performance as it doesn't require IPC.

However, there's no instructions on HOW to run the automation server as in process. Is it possible? If not, why mention it on the Automation Server documentation page?
