Can installing Lubuntu instead of Ubuntu help in decreasing the processing time of my program on an embedded system?

I've written a machine vision processing algorithm on an embedded board which is going to be installed in the outdoor environment. The embedded system consists of an Intel Atom Dual Core processor which clocks at 1.8 GHZ and has 4 GB of RAM.

My algorithm needs Qt and OpenCV to be installed on the operating system to run properly.

Can installing Lubuntu instead of Ubuntu help in decreasing the processing time of my program? For example, could I have a 20% or more reduction in my algorithm processing time by just replacing Ubuntu with Lubuntu? If yes, how could it be measured before installing Lubuntu on my embedded board?

I want to know if there's a huge reduction by just removing some fancy features of Ubuntu since I'm not going to use them at all. If not, I don't want to bother my self installing Lubuntu and perform all the tests again.

The generic answer is Yes it could. But only testing it will tell you for sure. I have an Atom dual core board with 2 GB of RAM that run Ubuntu on and I never go for full blown Unity or Gnome desktop environment on it. I prefer Lubuntu or LXDE and I install stripped down versions of them (without bloatware).

Try this:

sudo apt-get install --no-install-recommends lubuntu-desktop

Or if you want raw LXDE then this:

sudo apt-get install lxde-core

Or for a stripped down version of Gnome 3 use this:

sudo apt-get install xorg gnome-core gnome-system-tools gnome-app-install

Or if you want to stick to Unity (not recommended) then use this:

sudo apt-get install --no-install-recommends ubuntu-desktop

My opinion is that you will see that LXDE or Lubuntu will help. But like Aditya mentioned, Xubuntu is also good. You may either of them and optionally include the --no-install-recommends modifier.
