I have a strange problem describes as follows:
I have wrote a network device driver and
tried to test its performance by using Smartbit.
The driver performance is 18 Mbps when I use "insmod driver.o".
But it is 22 Mbps when I use this driver as "built-in kernel driver".
Why the performance result between "Module" and "Kernel" is different?
Does this result reasonable?
I need your suggestions. Thank you!
