Re: [PATCH v2 0/4] timer: Improve itimers scalability

Removing dependency to the database code is trivial. It's just 100 lines that launch lots of threads and do NUMA-aware memory accesses so that remote NUMA access cost does not affect the benchmark.

It's just a bit tedious to convert the C++11 code into C/pthread.
C++11 really spoiled me.
Still, not much work. Let me know where to post the code.

Yes, sure. At the moment, this micro benchmark is written in C++ and
integrated with the database code. We can look into rewriting it into a
more general program so that it can be included in perf.

Thanks,
Jason
