- The execution time is almost the same as ex3.
- But, in this case, after increasing number of threads
- 4->10 and 10->100, the execution time sometimes
- insignificantly increased (it happened before
- several times). It is probably caused by
- mutexes, since they don't allow multiple threads run
- the locked code at the same time. The number of
- threads is way higher than the number of physical
- cores and the most of them don't even work at the same
- time because of mutexes. The increased amount of
- execution time is probably caused by the overheads of
- threads and mutexes.
