I made my first program at a big data course and profited to make a little study about the performance of my pc and my laptop, testing it in several systems and virtual images.

I found both computer slows down when the system has installations.

I expected to find lubuntu a bit faster than kubuntu but this is not what I found. I do not know basics of informatics and I wonder why so.

The result of the study was:

enter image description here

1, 2 and 3 are statical mean of the three methods of the program launching it 10 times. Total means total time executing the program 10 times.

My laptop has an i5 and 8Gb RAM, 250 GB disk

My pc has an i5 and 16GB RAM, 1TB disk

    Without information about what these numbers mean, this question will be difficult to answer.

    Programs do not automatically run faster on the same hardware when you use Lubuntu instead of Kubuntu. The only difference is that Lubuntu will use less resources (less memory etc.) than Kubuntu.

  • Why did you assume Lubuntu to be faster?

    By the way, Kubuntu 17.04 is no longer supported. You may want to upgrade to 17.10 (with support for a few more months) or to 18.04 which will be supported until April 2021.

Lubuntu and KDE are 2 Desktop Environments that both lie on top of a similar Linux Kernel.

Lubuntu is a lighter DE yes, meaning you have more resource left to have things open and better all round stability (resource wise) but that doesn't mean it will run software's faster.
