Hi, folks,
I did kernel profiling when a single thread client sends UDP packets to a
single thread server on the same machine.
In the output kernel profile, the first few kernel functions that consumes
the most CPU time are listed below:
granularity: each sample hit covers 16 byte(s) for 0.01
Forgot to meantion that the test is based on FreeBSD kernel 7.0 2000807
snapshot.
The kernel was compiled with a modified version of GENERIC configuration.
With SMP and PREEMPTION disabled and kernel profiling enabled.

Many thanks for the information.
Could we say that interrupt handlers consumed ~36% execution time?
Is this number too high? Is it possible that we abuse the use of critical
sections in kernel?
Looking forward to your options. Many thanks.
