 === Performance
 A system that performs well provides a positive user experience. Users expect applications and services to respond promptly to their requests. A higher performance leads to increased user satisfaction and engagement. Also, a good performance help to get a better efficiency.
 
-We are going to look for a good performance with the code optimization, wihout overloading the system and memory and doing some performance test.
