Raspbian Lite uses less cpu?

Question

Does Raspbian lite version use less cpu / memory than the full Raspbian. I know the lite uses less storage for sure but not sure on the cpu memory.

I am running some time critical code I am thinking might improve if I switch to Lite because the cpu is doing less of other stuff?

I am trying to capture 2 images simultanously. I have 2 pi zeros attached via usb otg to a pi3 and a simple python udp program that sends a message from pi3 to both pi zeros to capture. However I'm getting images up to 100ms apart.

Raspbian Lite doesn't have any GUI. It has only a command-line interface. If you want to work on Raspberry with Lite version then you should have a basic understanding of commands and file system of Linux. And Raspbian Lite uses less CPU and memory uses because of no GUI.

Having more software installed doesn't have any impact on the CPU/RAM unless you run that software. Run raspi-config and disable desktop environment, and after a reboot you will get a system which will be pretty close to Raspbian Lite performance-wise. If that provides the performance boost you expect, you could permanently switch to Raspbian Line. I wouldn't hold my breath though.
