=== Performance Comparison ===fork() total time:           %.6f s (avg: %.3f us)
pthread_create() total time: %.6f s (avg: %.3f us)

Explanation: fork() creates a new process with a copy of theentire address space, which is much heavier than pthread_create()which only creates a new thread sharing the same address space.Iterations: %d
Ratio (fork/pthread): %.2fx
