From the title, I thought Microsoft had sponsored an improvement in generic FreeBSD.

From the revision, it seems the improvement is in a Hyper-V storage driver.

Indeed, Microsoft has done quite a bit of work towards increasing the performance of FreeBSD running on Azure / HyperV.

Yes, they're doing this with Linux too. I recall reading an announcement about 20kLoC worth of their patches to the Linux mainline kernel, in order to improve performance on Hyper-V.
