Best Operating system for developing email and camera

[dalepi]

Can any one suggest me with best operating system to develop email notification system which shoots email every interval of time with an image capture by a camera connected to pi (multiple cameras same time). experimenting with couple of operating systems. Ubuntu Mate and Noode, Mate seems slow at processing because of it's heavy GUI. Looking for light weight OS that can process bit faster.
Thanks in advance.

The OS should have very little to do with the speed of this application.
You should be able to script this in Python easily.

Any Operating System should work ?

Sure. Why not?
It’s not like this is a realtime application.

I’d start with Raspbian Jessie (mostly since it’s the most widely used, and has the best on-line support).
