Thanks for your suggestion.
We will look for real scenario to test, and could you please introduce
some benchmarks on spinlock ?

The kernel has been well optimized for most common workloads that
spinlock contention is usually not a performance bottleneck. There are
still corner cases where there is heavy spinlock contention.
I used a spinlock loop microbenchmark like what you are doing as well as
AIM7 for application level testing.
