+На скринах заметна зависимость производительности программы от количества потоков: чем больше потоков-
+тем быстрее программа.

+С увеличением количества процессов, скорость работы программы так же увеличивается.
+Но скорость программы также зависит от количества логических ядер компьютера, если количество
+процессов будет их превышать, то это несущественно скажется на производительности программы или даже
+снизит ее.
