Above answers are correct.now I tell why?
1. Critical Section Object works faster because Critical
section is a user object and is specific to a process.
Where as a Mutex is a kernel object and so many
processes running over the kernel can lock or
unlock/release it. So it is a bit heavier than Critical
Section and thus slow.
2. When control enters the critical section the interrupts
(from various devices like FEC, UART etc. ) to the CPU core
are disabled
