Dear experts

we have a systems with Ubuntu Linux 2.6.25.11 and Xenomai 2.4.4.
The system has a Pentium III (Coppermine) 1GHz.
The Xenomai installation seems to be ok.

I generate a periodic event based on a ISA irq every 2 msec. and also seems
to be right.
When we generate events in the human interface (open windows, ecc..) we
don't respect the deadline of 2 msec.

Pentium III is an obsolete system but we are wondering if this loose
performances depends on it.
It would be useful to know if this is a supported hardware and if is known
the related maximum IRQ latency and the maximun IRQ jitter.

Thanks in advance

Stefano
