Thanks Alan,
any hints on how to verify and eventually correct?
I saw some references about irqpoll kernel parameter but with
performance issues drawbacks...

Another important thing to say furthermore, is that the same drive
connected to a dual athlon xp machine with standard ide channels
worked tipically at 5x-8x during dvd isos burning activities with
centos 4.4 os. And analogous results on the same machine with fc5.

First tests on this fc6 machine show a speed that is not faster than 2.60X ;-(
burning sw is k3b in all the cases.
Is there any driver optimization parameters here? are others using
JMB363 experimenting same performance issues?
