If you have a stream of individual I/Os and the processing of the I/Os
takes more time than the time between the I/Os you need threads.

No, the processing beetween the I/O can mostly depend on other I/Os,
which is the standard case for server applications.

 In that situation, multithreading isn’t going to speed things up.

ummm, so what does the server do after getting an io completion...?
It has to do something. Look something up in a RCU protected database structure, ect, ect... Thread sync scalability usually becomes an issue right when your server experiences any type of decent load. Especially heavy load! ;^o
