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:
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
