[OpenIndiana-discuss] VirtualBox on OI

[Chris Mosetick]

Yes, I have tweaked the block sizes on my virtual box guests zvols to get
the desired performance.

there are two factors that you may want to look at:
>
>  1) block size.  files default to a 128K allocation block size, while
> zvols default to 8K.
>
>  2) check the "sync" property; the zvol may be generating synchronous
> writes while I/O to the file isn't.
