Speaking anonymously, LEROY Christophe told us:

Hi,

I thought that Montavista had really improved the realtime of Linux,
but i've been told that Montavista has only improved realtime for threads
and for SMP.

I guess you'd have to try it and see for yourself.

It means it is only interesting if you have only one process per CPU, with
a lot of threads inside it.

Is that right ?

If it is right, I can't see any interest of using Linux for embedded
systems.

As someone else wrote, Montavista Linux isn't the only real-time or
embedded Linux. You might have a look at TimeSys Linux:
