And generates much less interrupts per second, because each zaptel device have its own clocking interface...  Zaptel
device generates an interrupt every 1 ms (1000 interrupts per second), so 2 or 3 cards will generate about 2000 or 3000
interrupts every second, and not all host CPUs will handle them successfully. In this situation to minimize IRQ flow
better is to:
a) have "as-much-as-possible" ports on signle card;
b) distrubute cards between different hosts.
