[Xenomai] cpu with one core only

Hello,

It is said in documentation:

"The key issue is with the number of CPU cores actually running
real-time threads and receiving interrupts from real-time sources, not
with the overall number of cores on line on the target hardware.
Because the Cobalt co-kernel does not share any lock with the regular
Linux kernel when dealing with real-time activities, a 16-way server
pinning such activities on not more than four of the available cores
would still deliver good performances in a Cobalt-based dual kernel
configuration."

We plan to use xenomai,
but the cpu (Atom) is only a single core.

Can a single core still gives good results with xenomai ?

Regards,
Ran
