Hi!

For an environment with very heavy parallell IO, should the performance be just as good in a BHyVe guest as in the FreeBSD host environment?

What I thought of is that I guess within the host environment, the storage subsystem should have all kinds of optimizations like an internal work queue that pushes lots of work alinearly/asynchronously to the disk controller and this way allows it, in turn, to give all its performance.

Does the virtualized disk interface carry over all that goodness to the guest?

(https://wiki.freebsd.org/bhyve seems to say yes, presuming you configure BHyVe to run the virtual disk in AHCI mode?)

Thanks!
Tinker
