In my opinion a more accurate measure when you go down to the micro seconds level is TSC directly from the CPU. I've built a benchmark tool for that https://github.com/sh4ka/hft-benchmarks

Also I think that CPU pining could help in this context but perhaps I need to check the code in my machine first.

How does this compare with divan?

		Divan is what I used as reference for some parts of my work (mostly the CPU timestamp parts). My project is less complete, but it will also include other important benchmarks for HFT, like current network I/O or some real trading patterns like order placement overhead.
