Have you still got 2 CPUs defined? Use only one.

no Doug, it's not

it's all the afternoon that i'm running with just one CPU
and i've the stack ip that works completely randomly

(also see that with 2 cores i ftp at 8MB/sec
with one core at 4MB/sec it's not acceptable speed
so if my speed is limited to 4MB/sec i will not use virtual box at all)

i've seen before this kind of issues
in the past there were IRQ conflicts (on bare metal)
