Hi Gianluca,
You are right, in oVirt 4.2 we removed the 'Num Of IO Threads' text field
from the UI because it was decided that one IO thread is the best
configuration from performance aspects for most cases (according to
performance testings). We wanted to keep the UI simpler to use.
So in case IO threads is enabled via Webadmin UI, only one IO thread is
always created.
For REST API the configuration remains unchanged in 4.2, so you can still
set the number of IO threads to be >= 1 if you want for some reason.

Thanks for confirmation.
So I think the manual has to be updated.
Let me know if you want me to open a documentation bug or not.
Have you any suggestion on how to set from the REST API, so that I can make
some tests?
Have you "permission" to detail better the scenario of your test cases,
landing to prefer 1 I/O thread?
