Hello,
Yes certainly dual machine has much better responsivity,
but even single CPU machine is not locked up during optimizing
(the AmiBroker tries to consume no more than about 90% of (single) CPU time
during optimizations, so 10% is left for the other tasks )
Hope this helps.
Best regards,
Tomasz Janeczko
