4. A multithreaded web server wishes to keep track of the number of requests it services (known as hits). Consider the two following strategies to prevent a race condition on the
variable hits. The first strategy is to use a basic mutex lock when updating hits:
int hits;
mutex_lock hit_lock;
hit_lock. acquire();
hits++;
hit_lock. release();
A second strategy is to use an atomic integer:
Atomic_t hits;
Atomic_inc(&hits);
Explain which of these two strategies is more efficient.
