  1. The execution time is almost the same as ex3.

  2. But, in this case, after increasing number of threads

  3. 4->10 and 10->100, the execution time is

  4. insignificantly increasing. It is probably caused by

  5. mutexes, since they don't allow multiple threads run

  6. the locked code at the same time. The number of

  7. threads is way higher than the number of physical

  8. cores and the most of them don't even work at the same

  9. time because of mutexes. The increased amount of

  10. execution time is probably caused by the overheads of

  11. threads and mutexes.
