I don't know why you keep saying that the MCS manager requires too much 
memory. It does its job and I'm not sure it uses more memory than other 
components.

If I look at the values on my system, I see nothing wrong with MCS 
manager memory usage:

mcs-manager
===========
Virtual memory: 89.8Mb
Resident memory:7.2Mb
Shared memory: 3.6Mb

Compared with other components:

Thunar
======
Virtual Memory: 101.1 Mb
Resident memory: 13.5 Mb
Share memory 8.2 Mb

Terminal
========
Virtual memory: 81.4Mb
Resident memory: 17.2Mb
Shared memory: 7.9Mb

xfwm4
=====
Virtual memory: 62.7Mb
Resident memory: 8.9Mb
Shared memory: 6.1Mb

xfce4-panel
===========
Virtual memory: 75.6Mb
Resident memory: 11.4Mb
Shared memory: 7.1Mb

Ubuntu update notifier
======================
Virtual memory: 96.4Mb
Resident memory: 11.5Mb
Shared memory: 8.4Mb

xfdesktop
=========
Virtual memory: 97.0Mb
Resident memory: 12.6Mb
Shared memory: 7.8Mb

Now about startup time. It's usually the first component to run, so it 
has to load all of the missing libraries. When I look at the numbers (by 
enabling --enable-loadprof for example), I don't think it's that much of 
a problem :

(I suspect the ui plugin is taking longer because it affect gtk apps and 
the mcs manage ritself is a gtk application, and therefore it has to 
update its theme and engine in the same time)

Cheers,
Olivier.
