Beginner question: output a number

[Rolander]

Please tell me why the profiling results are always different in each time the program runs ? the differnce is not much but why it exists? Thank you

[Hobson]

Thats because every time you run your program, external conditions are different: antivirus software scans some files or not, your program has to retrieve data from swap file or not, in a given moment network works faster or slower, some process enters tight loop and takes a lot of processor time, etc etc. Things which happen inside of your OS also influent performance of your program, and hardly ever you can do anything aobut that.
